also talked about use of drosophila for his experiments and how it lead to understanding that some traits get passed on because they're on the X chromosome. not sure if i'd get full marks for it tho
wasn't too bad, hoping for 88-95 raw. found that there were quite a few 4 mark questions that i'd have though should be worth 2-3 marks. oh well, reckon i went into enough detail anyway. :)
seems like all the science exams were easy this year.
