Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.
Irina-Kira [14]

<u> Allele frequencies to change from one generation to the next.-</u>

<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>

  • Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
  • When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.

Why do allele frequencies change from one generation to the next?

Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.

No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.

What are 5 factors that cause changes in allele frequency?

  • A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
  • These include natural selection, gene flow, genetic drift, and mutation.
