I thuoght Q1 was binary fission fml

[onerealsmartass]

OH few felt soooo down

[thushan]

i put 24C as

- anatomy of flagella are different
- functions are the same
- the species do not have a recent common ancestor, you had to go back to the kingdom to find their common ancestry

so analogous structures

[lexitu]

Okay, hmm damn. I agree with you now. The last line says it all.

[onerealsmartass]

[stonecold]

here are my answers

CBDDB BCCCD BAADB DCDDB ABACA

i put 23A as:

- proportion of heterozygous individuals skyrocketed as soon as DDT spraying reduced
- in 1966 the percentage of heterozygotes was similar to number of homozygous resistant, something like 50 homo dom, 40 hetero, 5 homo rec

say 50 RR, 45 RS, 5 SS --> no. R = 145, no. S = 55

so C is not right, unless i made a mistake?

yeah, it is A.  he had it as A before and mixed it up.

It is clear heterozygous advantage occurred, as their frequency is higher than that of the other 2.

[thushan]

Yeah I deleted the post when I saw your edit whoops

[slothpomba]

Haha my face was almost glued to the exam paper, trying to see if the line was on 0 or not for the heterozygous advantage question

That wasn't actually necessary.  I was doing the same thing, then realised it couldn't have hit 0, because then it would never come back up.
