Which of these variables is likely to undergo the largest change in value as the result of a mutation that introduces a brand-new allele into a population's gene pool at a locus that had formerly been fixed?

Average heterozygosity is a measure of the proportion of individuals in a population that are heterozygous at a particular locus. If a new allele is introduced into a population's gene pool, it is likely to increase the number of heterozygous individuals, and therefore increase the average heterozygosity. Nucleotide variability and geographic variability are measures of differences between populations and are less likely to be affected by a single allele introduction. The average number of loci is a fixed value and is not affected by changes in individual alleles.
