Question

Read the principle and answer the questions :
"Allele frequencies in a population are stable and constant from generation to generation called genetic equilibrium."
(a) Name the principle mentioned here.
(b) Mention any two factors affecting the equilibrium.
(c) What is the significance of disturbances occur in the genetic equilibrium?

Answer 1

a) The principle mentioned here is Hardy-Weinberg principle.

b) Two factors that affect Hardy-Weinberg equilibrium are

1) Mutations

2) Gene Migration

c) Significance of disturbances occur in the genetic equilibrium-

A disturbance in genetic equilibrium such as non-random mating, small population size, immigration or emigration, mutations or natural selection will result in evolution.
