Question

Which is true if a population is in genetic equilibrium

a) Evolution is occurring

b) new species are evolving

c) allele frequency is changing from one generation to the next

d) allele frequency is remaining the same from one generation to the next

Answer 1

A) Evolution is occurring. Evolution is measured at the population level with genetic equilibrium as the standard. According to the Hardy-Weinberg principle, both the ratios of genotypes and the frequency of alleles remain constant from one generation to the next in a sexually reproducing population, provided other conditions are stable. Hope this helped :)

Answer 2

D. This means the population is not changing. Think "equal" when you see equilibrium.
