Question

How is the equilibrium affected by variation lead to speciation?

Answer 1

Answer:

Some of the major factors which affect the genetic equilibrium and induce the variability in population are as follows: (A) Mutations (B) Recombinations during Sexual Reproduction (C) Genetic Drift (D) Gene Migration (Gene Flow) (E) Natural Selection.

According to Hardy-Weinberg Equilibrium law, the relative frequency of alleles in the population remains constant from generation to generation in a population of sexually reproducing organisms when:

(i) The population is large enough so that accident of sampling may be ignored

(ii) Mating takes place at random;

(iii) Mutation does not take place or if it does, the rate is same in both directions

(iv) All the members of the population survive and have equal reproduction rates
