Give one example of how allele frequencies change from one g
Solution
Answers:
Change of allele frequencies due to the said factors have been discussed below:
Mutation:
Mutations introduces new alleles into a population and can affect allele the allele frequency in the population.
Migration:
The movement of new individuals into or out of a population results in a change in allele frequency. Immigration results in addition of new alleles to a population while the reverse results in a loss.
Genetic drift:
It occurs due to a change in allele frequencies in a population by chance. Genetic drift is a random process and result in large changes in population within a short interval.
Non random mating:
Unless accompanied by selection, non random mating change the genotypic frequencies but not the allele frequencies in a population. The most important form of non random mating is inbreeding.
Selection:
Selection occurs when genotypes have different reproductive successes. It acts as a positive filter and removes alleles which has negative influence on a population while selects those which have positive or neutral effects.
