Hardy-Weinberg Conditions

Free
APBIO-9JBX17

The Hardy-Weinberg equation that is used to describe allele frequencies in a population was independently proposed by both British mathematician G. H. Hardy and German physicist Wilhelm Weinberg in 1908. Hardy-Weinberg equilibrium introduces an alternative to Darwin's suggestion that evolution is a continuous process. Hardy-Weinberg equilibrium is the idea that, under certain conditions, evolution will not occur. In this situation, the frequencies of the alleles for a gene locus will remain constant over time.

Which of the following populations is MOST likely to be in Hardy-Weinberg equilibrium?

A

A population displaying sexual dimorphism.

B

A population exposed to a recent nuclear power plant accident.

C

A small population colonizing a new island.

D

A large population in a stable environment.
