The Hardy-Weinberg principle:
A) states that allele and genotype frequencies change from generation to generation in a population at genetic equilibrium.
B) shows that if the population is large, the process of inheritance by itself causes changes in allele frequencies.
C) allows biologists to calculate allele frequencies in a given population if we know the genotype frequencies, and vice versa.
D) represents an ideal situation that seldom does not occur in the natural world.
E) is not essential to understanding the mechanisms of evolutionary change in sexually reproducing populations.

Question

Quizplus · Accepted Answer

The Hardy-Weinberg principle provides a mathematical model that allows for the calculation of allele frequencies from genotype frequencies in a population, and vice versa, assuming the population is at genetic equilibrium. This principle is fundamental in population genetics for understanding how allele frequencies predict the genetic composition of future generations under certain conditions.
