Post Exam Discussion

[Biology24123]

Overall, the exam was alright, about the same difficulty as last year. But some of the questions were really cryptic - couldn't even tell for sure what the question wanted.

It was harder than last year. There were no easy genetic cross questions in this one

Ermagherd.

IMO, that was definitley harder than last year, way less easy recall marks and no experimental design! (Unless I missed it oops)
I definitley bombed..... Reduced workload is not looking as probable for next year after that.

I also did Out of Africa, purely because I completely forgot what the Multiregional hypothesis even was 
Also, did ADP+Pi count as one of the input molecules for the light dependent reactions?

Most people did out of Africa I think

[Gromekk]

I think adp + Pi should be alright

[The Peasant]

Lol I still dont understand why it's multiregional. I know I screwed that question up, so I'm probs wrong.

What did people get for the mc with the trait involving the mtDNA?

[Yacoubb]

Guys just remember that a hard exam means that A+ would be granted for a lower percentage than normal! General consensus from what I've heard is that it was a tricky exam!

[The Peasant]

Also, what did people write for the fish hypothesis? The one with different fossils in different strata?

Yeah I screwed up the Africa as well, that multiple choice was d I think

I put that ocean predators were introduced in the middle of the time period, creating a selective advantage for a large dorsal spine as it would scare away the predators. Then the predator died out and spine sizes returned to normal gradually.

Do you think that would be right/get a mark??

For the 1 mark question, I said the environment changed from freshwater --> ocean like water --> freshwater.

I just said the change of water salinity

Was the trait supposed to be X linked?

[cosine]

I said out of africa wtf?
How is it multi regional wow i cant believe i did not realise this, add another 5 marks to my misfortunes...

I said out of africa because it said modern humans came from africa, and that modern humans did not share neanderthal DNA. wow....

[cosine]

Was the trait supposed to be X linked?

no it was mitochondrial, so only from mother to offspring, i got d too

I said out-of-africa aswell.

Can somebody explain to me how it's multi-regional hypothesis?
