Population genetics throughout the history of genetic medicine, investigators have taken advantage of unique human populations with particular characteristics that lend themselves to genotype (individual) and phenotype (environmental) analysis. Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time many of the genes found within a population will be polymorphic - that is, they will occur in a. Population genetics instead focuses on the overall gene pool in a population of interbreeding organisms - that is, the frequency of all alleles of all genes in the population - and whether the gene pool may be changing across.
