Mutation

Vedclass · Answer

Given certain conditions, the allele frequencies remain constant from generation to generation. Under these conditions, a population would be in equilibrium and there will be no evolutionary change. However, many evolutionary changes usually occurs, following the appearance of new alleles and source of this mutation.

Genotypes :	$BB$	$Bb$	$bb$
frequency :	$22\%$	$62\%$	$16\%$

In a random mating population in equilibrium, which of the following brings about a change in gene frequency in non-directional manner?
