I feel that there will be 2 of the 6 mark question.
I do have a feeling that one of them is something related to genetics like epigenetic modification and polygenic inheritance.
The question may come as a table with many inherited features and the protein(enzyme/hormone) or gene responsible for it. And ask us to assess the table to explain the chances of organism X being for example of long body and ebony in colour referring to how the epigenetic modifications are responsible for this and the actual ratio and the expected ratio if the parents of organism X are.....

I think two 6 marks questions will be related to modern drug trial and anatomical, behavioural, physiological adaptations.

GOOD LUCK GUYS!!! hope unit 2 will be better than unit 1,,,<3
Guys my exam was terribly bad. I found the paper too hard
Original post by lilyyyana
what did u say for the epigenetics question?
Exon and intron thing. Sometimes spliceosoms cut the exon part as well, so the protein gets different
Original post by newlad632
It was soo different compared to the recent papers. I found it extremely difficult
Same here man. I felt like crying in the exam

Damn did anyone manage to finish the last 6 mark question?
No. There was a twist in the question. The animal was endemic. So we cant exchange seminal fluid of animals from different places. I didnt even understand what to write. And time was so less. There were many questions. It was so hard paper. I never found any paper so diffcult and never run out of time

Weren’t the graphs so confusing and needed time to just process and understand what the hell was going on????
I know right. I didnt understand anything. What the hell were we supposed to write. I didnt even understand the question and the time was running so fast
