In which condition, the gene ratio remains constant for any species : -
A
Sexual selection
B
Random mating
C
Mutation
D
Gene flow
Detailed Solution
The Hardy–Weinberg principle states that allele (gene) frequencies in a population remain constant from generation to generation if certain conditions are met.
These conditions are: a large population, random mating, and no mutation, no migration (gene flow), no genetic drift and no natural selection.
Sexual selection, mutation and gene flow all change gene frequencies.
So the gene ratio remains constant under random mating (along with the other conditions).
