A) nucleotide variability
B) chromosome number
C) average heterozygosity
D) nucleotide variability and average heterozygosity

Question

Quizplus · Accepted Answer

When loci are "fixed" in a population, it means that there is only one allele present at each of those loci for all individuals in the population. This results in lower nucleotide variability because there is less genetic variation at the nucleotide level. It also leads to lower average heterozygosity because there are fewer instances where individuals carry different alleles at the same locus, reducing the overall heterozygosity of the population.
