Title: Genetics and the evolution of life (BIOL10005): Exam thread
Post by: Starlight on October 09, 2012, 08:19:21 pm
Just wondering how everyone's approaching the exam in terms of studying.

I myself hate cramming so i've knocked out 7 lectures for the moment (genetics) and am memorizing 3 lectures every second day (plus trying to study 3 other exams at the same time because of my hectic exam timetable).

I hate zoology >.< so many terms!! Also (offtopic): practically failed the plant prac today :'(

I don't do this subject, but I envy your motivation and work ethic! I'm trying to begin exam preparation too but it's a bit of a struggle, getting started is the hardest part :@

Of course haha.

I'd start out by writing your own exam study timetable, i've made a calendar with the days i'll be studying certain lectures of subjects.

Also make a checklist of the lectures you have covered :D

Yeah I really need to write out a study timetable I think, at least it will keep me on task. But I really don't like using something this rigid it seems rather, well, lame... :P lol I like to try keep up with it myself, but I guess I really should do that.

Also memorising 3 lectures every 2nd day! :O GOOD JOB! Pat on the back for that :) Do you memorise the entire lecture slide? Like all the theory/definitions, questions/examples etc?

Lol not word by word. Just the key points, I mean for things like chemistry it's more like 30% memorizing, the rest is practice exams. Sometimes I think you just have to 'predict' what is going to be on the exam.

@El2012 So you just memorise the  key points from each lecture? How do you manage to do that? I don't think I could memorise every lecture.

How are you going to study for the Intercultural Communcation exam? Do you think anything from the guest lecturers will be on there?

No idea claireb, I just hope for the best and if i've learnt it before, like in high school or it's common knowledge there's not really much of a point in looking over and over that concept when I could look at new concepts.

Nah nothing like that sherpa lecture, I think it was more of an insight into ethnography of communication.

Ahh well.. if i actually were going to be doing summer subjects it would probably be biology. And i do hope it isn't , well, for any of my subjects actually!

And, Ummm.. your question confused me though - did you mean it seriously or going along with the joke of my predicted failure for the exams lol?

Ahh just bio in general - never really liked it - and when i say that, i refer to the genetics section. Each time i somehow get the strength to study the section on genetics I get this feeling of... suicide - best way i could put it. Never done bio in high school so yeah fun times!

Yeah it would probably be hard with terminology and just solving genetics problems.

Genetics is probably my favourite for the subject though..

At least in genetics there isn't a lot of terminology but there is so much for evolution -.-

No. I heard that they can be used to check your attendance if you fail (get 49%) to giving you a pass.. but how can they possibly know you have attended a tutorial anyway? I switched tutes because I had a god awful tutor in thursday's tute class.

I just did the 3 questions for populations genetics from the lecture slides; it wasn't that bad actually, kind of makes sense to me now :P

I've done 6 lectures of revision!!! That's 6 more than last semester :P

Well i agree Zoology has a lot of terminology that is near impossible to learn. But i found zoology lectures to be the most entertaining! I just like learning about evolution and biodiversity for some reason ..

Is there a quick/simple way of calculating ratios for dihybrid crosses??

Like this question:

Quote
In peanuts the phenotype may be either ‘bunch’ or ‘runner’. Two purebreeding bunch plants were crossed and the F1 were all ‘runner’. Allowing the F1 to interbreed produced an F2 with 173 ‘runner’ and 147 ‘bunch’. Propose a genetic hypothesis to explain the inheritance of this trait in peanuts.

All i know how to do is the percentage of each phenotype (173/320 and 147/320) but i don't know how to turn those into ratios :/

I'm guessing some mathematical manipulation is required but i'm terrible at maths.

The percentage is 55% and 45% so i'm guessing it is 9:7 ratio and that both recessive genotypes are epistatic.

So (173/320) is 55%

so you're right just solve (x/16) = 0.55

and x= 8.8 so you can round up to 9 :D

Somebody please help me with this question :P

Well it rules out C because it's quantitative (i.e. not multifactorial, those are things like spina bifida etc. where it's present or not)

Use Height 188-190 (or 143-145)
I'll just use height 188-190 since it's the base height

so (1/1031)= (1/4)^5 (they are approximately equal)

so there are five polygenes (rules out a)  meaning they have the alleles:

AABBCCDDEE  (rules out b)

To get D:

Find the range= 188 (max height in offspring) - 145 (base height) = 43 cm

10 contributing alleles (AABBCCDDEE) = 43/10 = 4.3cm = close enough to the answer :D



Also: Try see if you can do the problem at the end of the polygenic inheritance lecture, it's the same method

Thanks El but i dont get why you used 1/1031 over any other trait?? That (1/4)^n rule is for finding out how many offpsring are related to the parent. But the question says nothing about that. How do you know it was 1/1031??

I used the (1/4)^n rule so i could determine the amount of polygenes, given by n. This has to be done to determine the number of contributing alleles (i.e. to rule out b)

I guess when I looked at when it said 1031 offspring, I was like oh hey that's close to 4^5. So i could say (1/1031) = (1/4)^5

Oh and also, none of the other numbers simplify, so they weren't something like (2/32 offspring so I could say 1/16 = (1/4)^2)

Does this sort of makes sense?

Don't worry I went through that stage too. And TBH I think most chem students are on the same page.

To me, the lectures were inadequate and I strongly encourage you to check the textbook for most of what they were discussing (it goes through things like nomenclature of coordination compounds, steady state approximation etc. pretty well).

What part are you finding the hardest?

Chemistry is seriously the worse run subject i've experienced. The lectures are terribly centred around on useless rote-learning; Practicals are always rushed and poorly organised to fit within the 3 hour time frame.

Even to the very last lecture it was full on you got to memorise this; memorise that without even talking about the exam. My other subjects mostly talked about the exam and/or gave an overview of the entire content learnt over the semester but not Chemistry...

Putting me off Chemistry so bad..

Haha from what i've heard, chemistry is much worse.

Chemistry fundamentals was soooo much better ran, they actually gave you explanations in lectures of how to solve problems and everything and the lecturers were way better.

Yeah that's the same as what I'm doing atm! Except I'm typing it out cos there is just too much to write, it'll be quicker and neater too :P If I have time I might try writing out a summary of that summary so just list the key ideas and terms associated with it and draw some tables/graphs or whatnot. I just want to get this study notes process over with, it's the woooorst haha at least when you're doing the questions actively you're both reviewing and applying the knowledge, whereas summarizing is boringly painful! :P

What are you (and anyone else) doing for chem? There are a lot of reactions and rules to remember (mainly for organic/incorganic) yet it is important to apply them with the questions too - hard to find a balance.

Well from past exam papers, I think i have come to the conclusion that i'm not going to really look at batteries (they don't seem to come up much, and if they do they are only 1 mark or so so i'm willing to give that up)

Is there any other reasons than chitonous Exo-skeleton for the success of arthropods??

I mean there are diversification of appendages and segmentation but i don't see how diversity in it of itself can contribute to success?? Like Arthropods have varying number of legs but how does that help with success?

Lol it was my tutor last sem who inadvertently told us haha.

Good question. Well I suppose you could talk about the sensory structures, nervous system and that some have flight also.

Also perhaps for the plant section:

•   What are the evolutionary steps that led to the development of land plants and most recently angiosperms? (Maybe the adaptations that were required for land plants to evolve?)

It found it easier than i had anticipated...Easier than last semester.

Section A was pretty straight forward apart from some of the genetic questions...I was relieved when we were told to cross out one of the genetic question on the exam and it was a really hard one!

Secontion B/C: The genetics component were the easiest this time. Struggled big time with naming the anatomy of the squid :(  And there was a question with pictures of fossils and we had to name them. A bit harsh since i'm pretty sure picture in her slides are not on the lms lecture slides..But i knew most of the fossil except the one where you don't know which side is up or down.. I put down some name related to hallucination..Don't know if that is right though.

Section D: pretty straight forward, the selection question caught me off guard a bit but at least it wasn't asking about specific class differences.

LOL i think you wasted a bit of time memorising all of the different class names!! So relieved hardly any questions required you to know much about classes.

The heterozygote in the test cross was written as  (_,_,orange) when in fact it should have been (_,_,red) because looking at the offspring, none of the 2 phenotypes with 400+ had the phenotype (_,_,orange) but one did with (_,_,red).

I was screwed over by this question as well and none of my friends seemed to notice the error. I think people just assumed it said red because it said that it was heterozygous. So I wasted minutes banging my head thinking *How the hell can the recessive gene be shown if it is heterozygous!!!*

Poor work by the people at biology, I didn't read question 34 but I'm guessing that was a screw up as well.

Different question. This was the linkage one where you had 3 different genes, one was for colour, and it was simply either red or orange. No epistasis/codominance, etc.

Was replying to el's question about 34a. Should have quoted

There was also a stuff up for chem too. I wonder if this is going to be the case for all exams.
There were? Do you remember which ones? Didn't even notice them... Whoops

Didn't notice any chem stuff ups, although I did find it annoying that we pretty much had to guess whether Ni2+ was tetrahedral or octahedral in a coordination compound with water, as I don't think people could actually know such a thing beforehand. I guessed tetrahedral because it was 2+ and it seemed more likely, but when I googled it after, I saw it was octahedral. Looks like I'm having no luck with these exams haha

I said octahedral. But I stuffed it up because I wrote all the ligands were OH! And I didn't write the coordination number fml.

Pretty sure the multiple choice. I heard someone ask the examiner about it behind me. The question was like "what is the oxidation number of the cobalt atom" in some coordination compound. Except the metal centre was chromium and the counter ligand was carbon monoxide (CO) so it was all confusing.

Oh right the Cobalt-Chromium thing. I remember that. Idiots. You would think they'd re-read the exam before they handed it out to about 1000 students.

When I read that question I almost shit myself - I was looking at it like, did I miss something? Since when...ahh.. oh someone help me..

There was another error on the Biology exam. The twins were II5 and II6, not II6 and II7.

Yea there were no twins II6/7 so i was confused....

But if the exam meant II5/6 then it would have been right since they were monozygous....i think

Man the fossils! I only knew one.. archaeopteryx.

Pretty much forgot about x inactivation, the angiosperms question was expected (but my fourth reaason was pretty crap), made up complete bs about the selection questions. Yeah I probably did waste a little bit of time, but I guess its bonus marks.

I got lucky with the fossils.. I knew about Acanthostega because of one of the questions the same exam asked what was unusual about the first tetrapods (8 digits). I knee of them were ammonites or trilobites; then i remembered trilobites were arthropods from the exam exam so i picked the insect looking thing as trilobite and the snail looking thing as ammonite. the bird one was pretty obvious.

I guess section D depends sort of on luck and how much you know about the topic. IF i have gotten a question about distinction between sub-classes and a question about DNA manipulation (methylation/acetylation) then i probably would've failed lol.

EDIT:

Just got an email from Dawn saying

Dear Students,

Unfortunately there were two questions on the exam today in which there were
errors.

Please be reassured that the questions affected by these errors will not be

Sorry to crush your confidence, but Ammonite was the Omastar looking thing and the Trilobite was the Kabuto type thing. They were both on there.

I happened to know all 5 fossils from completely distinct, random, separate phenomena. I remember looking through the lecture notes thinking "I really want to know what a hallucigenia looks like[/b], so I looked it up.

The others, I dunno. I just knew them lol.

Did everyone pick up the error in Section B Q 4 with the 3 point test cross?
The heterozygote in the test cross was written as  (_,_,orange) when in fact it should have been (_,_,red) because looking at the offspring, none of the 2 phenotypes with 400+ had the phenotype (_,_,orange) but one did with (_,_,red). I couldn't believe they could make such an error. And I don't think everyone was told either as no announcement was made.
For our one there was an error with a 3 point test cross question, but they gave marks because there was an error (in one word in the question) lol. They sent us the email (but I do BIOL10002).

What do you mean?

I got them right... Trilobite,ammonite and hallucigenia.

Trilobite = insect looking one
ammonite = the large snail
Hallucigena= spiky worm on both sides

Edit: maybe poor wording on my previous post i think..i didin't proof read it lol

The acanostega was the 8 fingered tetrapod i think and the bird was the archerotexy or some name like that...

The sample exam had questions about which species died during the two extinction periods so i had to learn about Trilobites (Cretaceous-Tertiary) and Ammonites (Permian-Triassic).

The Hallucigenia i vaguely remember the lecturer talking about how they named it so when they thought they were hallucinating lol.

And the 8 digit tetrapod was in one of the sample exam question so i knew what it looked like...

Sigh. That was me last semester. Except my exam timetable was even better... a 10 day gap between exam 1 and exam 2.
