Association genetics is the process of identifying alleles that are disproportionately represented among individuals with different phenotypes. It is a population-based survey used to identify relationships between genetic markers and phenotypic traits. direct extension of Mendel’s laws, molecular genetics, and the ideas of Darwin. Instead of genetic transmission between individuals, population genetics considers the gene transmission at the population level. Population Genetics.
