How much of monogenic inheritance do we need to know?

Also another question, what is 'multiple alleles?'

Multiple alleles refers to more than one allele controlling a specific trait.

A classic example is ABO blood typing.

3 alleles: I^A, I^B and i therefore 6 outcomes for genotype (4 outcomes for blood type)

Besides Carbon-14 what other radiometric dating techniques might be assessed?

Don't you mean more than 2 alleles controlling a specific trait?

Potassium, Argon and perhaps Uranium.

Thanks!!

Monogenic is just your basic inheritance, so you'll already know what you need to know (excuse my vague answer ahaha but I'm sure you know how to do a basic single gene cross)

Do we need to know about molecular biology in medicine (save from rational drug design)? Because there's a question on the 2007 exam 1 asking about 'one application' that we had supposedly learnt (which I haven't) and I checked the study design and it's not there...? Thanks


How are people going with getting all the VCAA exams done? I have so many to go

Don't pressure yourself to finish 40 exams like some people are doing - it's all up to how much you think you're ready. There is no "benchmark" for the number of exams you have to do. It's all up to the individual.

I think that's been taken out of the study design.

Btw is it a bad idea to do practice exams at this point? How are you guys studying? GOODLUCK everybody

good luck to you too!
honestly i don't know if its a bad idea... did a prac exam and realised still got a long way to go, with the exam only in what 5 days:(
guess it wouldn't hurt to do more prac exams, but yeh don't do any on the day before i guess...
its too hard lol

Very true indeed, but I have done no where near that many ahah :\ around 12 thus far. I really want to complete all the VCAA ones though.

good luck to you too!

Thanks guys! GOOD LUCK EVERYONE 

I'm still doing practice exams  Just want to fine tune my responses and whatnot!

Thank you! And around 15 thus far, want to complete 25 by thursday though!

I was thinking about that tbh... I think I might stop doing practice exams on wednesday. Probably chill on thursday or study for another subject... good idea guys?  Haven't sone a ¾ before so no idea haha.

good luck to you too!

Just remember in 5 days, A LOT can happen. You can basically revise the whole study design (in not much detail) but hey its better than not knowing anything!

Goodluck guys and keep studying! 5 days to go. Then we can burn our books

Definition of transgenic organisms? I've got "An organism that has foreign DNA artificially inserted in its genome"
But does the DNA have to be from a different species?

Foreign DNA suffices.

Is analogous structures structures that carry out similar functions but have a different structure?
Because in the answers for a practice exam it says they have similar functions + similar function but arisen from diff common ancestor

Any clarification would help, thanka

[nerdmmb]

I was told by a few people that we need to write what the independent and dependent variables are in an experimental design question. Is this true because VCAA's answers don't include them...

Thanks!

Analogous structures are structures that have different underlying anatomy/structure as they do not have a common evolutionary origin but have similar function and external appearance/structure as a result of being subject to similar selection pressures
