Which variable is likely to undergo the largest change in value resulting from a mutation that introduces a new allele into a po

dsp73

Answer:

b. average heterozygosity

Explanation:

From the available options:

a. nucleotide variability

b. average heterozygosity

c. average number of loci

d. geographic variability

Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.

The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.

Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.

Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.

When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.

<em>The correct option is b.</em>
