1. Population size is very large (no genetic drift
affecting gene understudy)
2. Population is closed (no gene flow)
3.No mutations are occurring at gene under
study
4. Mating is random with respect to trait
understudy (no sexual selection, selection, no inbreeding inbreeding
at gene understudy)
5.All genotypes in population have equal
chance of surviving & reproducing (no selection
at the gene understudy)
