Q.25
Fish Physiology and Biochemistry- ICAR JRF/SRF 2024
MCQ (Single Correct) +4 −1
In a population under Hardy-Weinberg equilibrium, what happens to the genotype frequencies over successive generations in the absence of evolutionary forces?
  • Hardy-Weinberg Principle:
  • The Hardy-Weinberg law states that in a large, randomly mating diploid population, both allele frequencies ($p, q$) and genotype frequencies ($p^2, 2pq, q^2$) remain constant from generation to generation in the absence of evolutionary forces:
$$p^2 + 2pq + q^2 = 1$$
  • Evolutionary forces that would alter these frequencies include mutation, gene flow (migration), genetic drift, and natural selection.
  • Correct Option: Option 1 (Genotype frequencies remain constant).
