Godfrey Hardy and Wilhelm Weinberg independently created models to describe population genetics. They concluded that several con
ditions needed to be met in order for genetic equilibrium to occur. Which of these is a condition of Hardy-Weinberg equilibrium? a. Individuals in a population must not be prevented from migrating or interbreeding.
b. Individuals in a population must be able to select their mates based on physical characteristics.
c. Mutations that alter the genetic makeup of the population must not occur.
d. The population must be small enough to track each individual within the population.
c. Mutations that alter the genetic makeup of the population must not occur.
Explanation:
According to Hardy–Weinberg principle, allele frequencies of a population do not change from generation to generation if:
a) The population size is large.
b) There are no operative evolutionary forces in the population. The evolutionary processes that disturb the Hardy–Weinberg equilibrium are mutation, genetic drift, gene flow and natural selection.
Hence, to keep the allele frequency constant, a population should not exhibit mutations.
