The equation, p² + 2 pq + q² = 1.0, describes

A) the process of evolution.
B) the size of a population.
C) the rate of speciation of species p and q.
D) genotypic frequencies of a nonevolving population.
E) evolution of a population.

Genotypic Frequencies

The proportion of different genotypes in a population, which can change over time due to evolutionary processes.

Nonevolving Population

A theoretical population in which allele frequencies do not change over time, effectively not undergoing evolution.

Speciation

Origin of new species due to the evolutionary process of descent with modification.
