Question

Please help! the hardy-weinberg equation is an expression showing the frequencies of 100 percent of the alleles for a specific gene in a population. which statement must be true if biologists show that both p and q are not changing over a period of time?

A. predators are killing individuals with certain traits.

B. mutations are occurring in the population.

C. there is no migration in the population.

D.the population is very small.

Answer 1

If biologists show that both p and q are not changing over a period of time, the statement that must be true is:

C. There is no migration in the population.

The Hardy-Weinberg equation assumes that certain conditions are met for a population to be in genetic equilibrium, one of which is the absence of migration. Migration can introduce new alleles into a population or remove existing alleles, which would disrupt the equilibrium and cause changes in allele frequencies (p and q). Therefore, if p and q are not changing, it suggests that there is no migration occurring in the population.
