Answer 1

Allele frequency is a factor within a population could be studied to determine whether the population is evolving.

Answer 2

It has to be allele frequency. I just read the PDF (I'm taking the test too) and a sentence says " if a particular allele's frequency changes over time, the population is evolving" This should be correct or I will throw my computer lol
