a population of crocodiles is said to be in hardy-weinberg equilibrium.
if so, which statement must be true?
no new mutations have occurred.
natural selection is placing pressure on allele frequencies.
new individuals are migrating into the population.
genetic drift is taking place.

Explanation:

The Hardy - Weinberg equilibrium has several assumptions. One of them is that there are no new mutations. If natural selection is acting (which would change allele frequencies), migration is occurring (introducing or removing alleles), or genetic drift is taking place (random changes in allele frequencies due to chance, especially in small populations), the population is not in Hardy - Weinberg equilibrium.

Answer:

No new mutations have occurred.
