Question 11

The Hardy-Weinberg principle shows that if the population is large, inheritance alone does not cause changes in allele frequency.
_______

Accepted Answer

The Hardy-Weinberg principle states that in a large population where mating is random, allele frequencies remain constant over generations unless additional factors such as natural selection, mutation, migration, or non-random mating come into play. Therefore, inheritance alone does not cause changes in allele frequency in a large population.

Question 12

A type of genetic flow called the founder effect occurs when a small number of individuals from a large population form a new colony.
_________

Accepted Answer

drift
