Genetic Drift: Defined As Stochastic Shift in Allele Frequencies. Variation in The Relative Frequency of Different

Genetic drift is defined as a stochastic shift in allele frequencies that occurs by chance in small populations as particular genes disappear when individuals die or do not reproduce, leading to variation in the relative frequency of genotypes. Gene flow is the process by which evolution can also proceed through the loss or gain of alleles via emigration or immigration between populations.
