GENETIC DRIFT AND GENE FLOW IN POPULATIONS OF THE GREAT GERBILS

The article describes the additional evolutionary factors, apart from natural selection, which can influence the genetic structure of the populations of the main carriers of the plague microbe – the great gerbil. The influence of genetic drift on random fluctuation of alleles is considered. With...
