Q.Who developed the concept of genetic drift ?

Microevolution — change in allele frequency within a population — is driven by four fundamental forces: natural selection (differential survival/reproduction of genotypes), genetic drift (random, chance-driven allele-frequency change, strongest in small populations), gene flow (alleles entering or leaving a population via migrating individuals or gametes) and mutation (the ultimate, though usually slow-acting, source of new variation). Alongside these natural forces, humans can act as a selective agent through artificial selection — e.g. the many dog breeds sel …
