The correct option is (D) Nucleotide variability and average heterozygosity 
The higher the proportion of loci that are "fixed" in a population, the lower are that population's nucleotide variability and average heterozygosity.
<h3>
What does it indicate when a gene in a population is fixed?</h3>
- In population genetics, fixation is the transformation of a gene pool from one in which at least two alleles of a certain gene exist in a given population to one in which only one allele persists. 
- Any allele must eventually be lost entirely from the population or fixed (permanently established at 100% frequency in the population) in the absence of mutation or the heterozygote advantage. 
- Selection coefficients and random variations in allelic proportions determine whether a gene will ultimately be lost or fixed. Fixation may relate to a specific nucleotide location in the DNA chain or a gene in general (locus).
