Fill In the Blank: A population that

A population that is not evolving at a particular trait is likely to be at Hardy-Weinberg equilibrium for that trait. (two words) for a given Microevolution is occurring if there is any variation in allele frequency trait. The random fluctuation in allele frequencies observed in small populations are collectively referred to as genetic drift (two words) Amish and Mennonite populations in the USA have higher incidences of some genetic disorders. This is due to a form of genetic drift called founder effect (two words) When a particular allele is favored by the environment, that trait is said to be undergoing Human females prefer male partners who have symmetrical features; this trait is clearly undergoing Female widowbirds consistently prefer the males with the longest tails. Male tail length is undergoing selectiorn selection selection (be specific!) Although the largest male elephant seals attract harems of females (that's the actual scientific term) (!), very small males will sometimes be able to sneak in a quick mating opportunity. Body size in male elephant seals is therefore likely to be undergoing specific) Natural selection is a nonrandom process that, with each successive generation, favors selection (again, be : the accumulation of traits that increase the reproductive success of an organism in a given environment. The movement of alleles between populations is referred to as gene flow (two words)
