Webkey to this are powerful classical and molecular genetic methodologies, imaginative approaches, and the ability to move between genetics, biochemistry and cell. Webgene pool, sum of a population’s genetic material at a given time. The term typically is used in reference to a population made up of individuals of the same species and includes all. Webthe gene pool is the sum of all the alleles in a population. Sometimes, allele frequencies within a population change randomly with no advantage to the population. Webpopulation genetics examines genetic variation within and between populations, and changes in allele frequencies across generations.
