short tandem repeat loci (microsatellites):Loci consisting of short sequences (2–6 nucleotides)  that are repeated multiple times. Alleles at short tandem  repeat loci differ from one  another in their number of repeats.

Genetic drift:The random fluctuations in allele frequencies over time that are due to chance alone.

Variance:A measure of the amount of variation around a mean value.

Diversifying selection:Selection in which different alleles are favoured in different populations. It is often a consequence of local adaptation (in which genotypes from different populations have higher fitness in their home environments owing to historical natural selection)

Hardy–Weinberg proportions:When the frequency of each diploid genotype at a locus equals that expected from the random union of alleles. That is, the genotypes AA, Aa and aa will be at frequencies p2, 2pq and q2, respectively.

Heterozygote advantage:A pattern of natural selection in which heterozygotes are more likely to survive than homozygote
