WebGenetic drift (also called random genetic drift) means a change in the gene pool strictly by chance fixation of alleles. The effects of genetic drift can be acute in small populations … WebGene flow — also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries. If genetic variants are carried to
