The Biological Question Thread

[matt123]

Co-dominance; incomplete dominance is not in the study design, so if VCAA asks a question and you are unsure about whether it is incomplete dominance or co-dominance (the ones where you have to split hairs), just put in co-dominance.

haha, I can tell you have been listening to douchy.

He has
AND OMG DOUCHY MENTIONED MY NAME ( MATEEN) AND MY QUESTION ( ABOUT EVOLUTION) IN HIS LAST PODCAST

EVERYONE GO READ IT
IM SO PUMPED
lol

[thushan]

LOL Douchy also mentioned my name - although he couldn't pronounce it properly

it came out as "thoosun"

[sillysmile]

really??? ah I kinda regret not asking him direct questions...
haha, maybe next year I will send some questions to make up for it.
or not.

I remember douchy talking about you thusan, but wat was your question matt?

[golden]

About the foramen magnum what would be a response about the position of the foramen magnum or how it has changed in hominins to allow bipedalism that is by VCAA standards?

[sillysmile]

the foramen magnum gradually became more centrally positioned at the base of the skull as a result of bipedalism (and greater balance), as opposed to quadripedal animals who have a foramen magnum positioned at the back of the skull

Sounds good. Thanks.

50th post.

If you were to breed a white flower with a red flower and the offspring were all pink would VCAA call this incomplete dominance or co-dominance? My teacher at school says its incomplete as its a blend of the two, but I've also heard that it would be co-dominance because in effect both alleles are fully expressed because there are both red and white pigments they are just such small 'dots' they appear to be pink.

What are your thoughts?

This is overthinking it way too much. Neither of the phenotypes observed in the parents are in the child, instead there's an intermediate phenotype. If you wanted to work out whether it was actually just "really small" sections of the different pigments, you'd need to do a biochemical investigation to check cell samples etc.

So until otherwise, incomplete.

I asked him
If we evolved from the monkeys lol.
And we are still here .. and they are still here.

why the hell arnt the "things in the middle" .. such as H.erectus and aferensis etc .. still here too?
how is it possible that they just "dissapeared "
lol

listen to the podcast
he answers it well

[thushan]

We need more biology teachers like Douchy!

[matt123]

We need more biology teachers like Douchy!

Agreed
my teacher is so bad .. I think id learn more if he actually wasnt there.
He gives you the WRONG information and isnt even certified to teach bio lols
our teacher left half way thru sem 1 and now were stuck with this guy.

and yeah I actually think I have might have a greater understanding of year 12 biology, than my biol teacher.
It sucks, because I think I would probably be much more knowledgable and motivated with a better teacher.

Yeah agreed
I think I easily ( with the VERY limited bio I have) .. know more than my teacher ...
eaaasilly . he marked out prac exams and gave me 9 marks less than i should have received.
He did the same prac exam in his spare time and got 62% ... LOL? .. I think a teacher shouldnt really get under 95% in any subject they teach.

I don't like to be harsh, but that's just pathetic.

[stonecold]

The day teachers are forced to sit exams alongside students will be the day we might get a decent secondary education system.

Teachers would go stupid and strike.  Shows how pathetic they are, and how they are afraid they might get exposed.
