Which of the following statements is NOT accurate? Choose all that apply.

	Inbreeding can change allele frequencies
	High levels of gene flow between two populations will lead to genetic divergence.
	Mutation is the process that creates new alleles.
	Genetic drift usually reduces levels of genetic variation within a population.
	Genetic drift can sometimes increase the average (=mean) fitness of a population.

Expert Solution

The inaccurate statements are-

1. Inbreeding can change allele frequencies

2. High levels of gene flow between two populations will lead to genetic divergence.

inbreeding does not in itself alter allele frequencies but continuous interbreeding increases the proportion of homozygous to heterozygotes in a population. Inbreeding increases the frequency of individuals with deleterious recessive genetic diseases.

When there is a great deal of gene flow between populations, they promote a homogenizing effect which also results in reduced divergence due to reduced power of natural selection.

The mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.

Genetic drift has a greater effect on smaller populations and can lead to a reduction in genetic diversity.

Genetic drift can result in evolutionary divergence so sometimes may increase the average (=mean) fitness of a population.

QUESTION 2 Select all the statements that are TRUE about what can change allele frequencies in a population over generations. Mutation: Mutation can change the allele frequencies by creating an allele that a population needs to survive when the environment changes. Which allele is dominant/recessive: Because the dominant allele is expressed more than the recessive allele, it is more likely to be passed on to offspring. Starting allele frequencies: In a small population, if the frequency of an allele is...
