MHT CET · BIOLOGY · STD 12 - 5. Origin and Evolution of Life
Select the INCORRECT statement from the following regarding evolution.
- A Mutation is the raw material for evolution.
- B Evolution occurs in the population.
- C Evolution is descent with modification.
- D Gene frequency remains constant due to non-random mating.
Answer & Solution
Correct Answer
(D) Gene frequency remains constant due to non-random mating.
Step-by-step Solution
Detailed explanation
Hardy-Weinberg's equilibrium law states that 'at equilibrium point both the gene (allele) frequency and genotypic frequency remain constant from generation to generation'.
Factors like non-random mating, gene migration (gene flow), genetic drift, mutation, genetic recombination, natural selection, etc. affect or change the Hardy-Weinberg equilibrium.
