Question

Why is a balanced frequency of different alleles of a gene in a population more useful for the survival of a population facing environmental changes?

Answer 1

ANSWER:

For a attribute conditioned by 2 alleles, for instance, A and a, a balanced frequency between the alleles A and b is a lot of advantageous for survival. for instance, in associate degree environmental state of affairs within which the aa homozygous composition becomes incompatible with life, the presence of an oversized variety of AA and Aa peoplecan end in a more robust likelihood of survival for the species. Another example is associate degree environmental state of affairs within which the dominant composition becomes incompatible with life; during this case, the existence of heterozygous and recessive homozygous people in giant enough numbers is also elementary for the survival of the species.
