Measuring Genetic Diversity in Human Populations

The major factor causing deviations from Hardy—Weinberg equilibrium is:

  1. a. selection
  2. b. nonrandom mating
  3. c. mutation
  4. d. migration
  5. e. early death

Summary Introduction

Introduction: The Hardy-Weinberg law states that in the absence of other evolutionary influences the frequency of allele and genotypes or genetic variation within a population will remain constant across generations.

Explanation of Solution

Reason for correct answer:

In the nonrandom mating process the most common effect is the inbreeding. In inbreeding mating takes place between closely related species. This form of mating creates homozygosity for all of the genes. As a result genotype frequencies get altered.

 Option b. is given as “nonrandom mating”.

The alteration in the genotype frequencies results in deviation from the Hardy-Weinberg equilibrium. Hence, the correct answer is option b.

Reasons for incorrect answer:

Option a. is given as, “selection”.

The process of selection will effect the frequency of allele in a population but the effect will not be so major that will disturb the equilibrium and cause deviation from the Hardy-Weinberg equilibrium. Hence, option a. is incorrect.

Option c. is given as, “mutation”.

The process of mutation will result in the formation of new alleles but the process of mutation is a very slow process...
