Question

Which of the following processes randomly effect (i.e. you cannot calculate the precise end result) the change in allele frequencies over time? (It is not all of them)

Sexual Selection

Natural Selection

Genetic Drift

Gene Flow

Mutation

Answer 1

Mutations and Genetic Drift

Step-by-step explanation:

A mutation refers to the random changes in the genome of the organisms. Being a random event, it is not possible to calculate the effect of mutations on the allele frequency of a population.

Genetic drift refers to changes in the allele frequency by chance event alone. Since the occurrence of chance events can not be predicted, the resultant changes in the allele frequency of the population can not be calculated.
