Question

56 factors that change allele frequency which of the following would change the allele frequencies of a population? multiple choice lack of mutation in the dna mating is random with no selection occurring a population on an island remains isolated and no one leaves or moves onto the island a small population is hit by a storm that kills off 30% of the population

Explanation:

1. Lack of mutation: Mutations introduce new alleles. Without mutations, allele frequencies remain stable in the absence of other factors.
2. Random mating with no selection: In random - mating populations without selection, allele frequencies follow the Hardy - Weinberg equilibrium and do not change.
3. Isolated population: In an isolated population with no gene flow (no immigration or emigration), allele frequencies remain constant in the absence of other evolutionary forces.
4. Genetic drift in a small population: A storm that kills 30% of a small population is an example of a random event (genetic drift). Genetic drift can cause significant changes in allele frequencies, especially in small populations.

Answer:

D. a small population is hit by a storm that kills off 30% of the population
