A population has three genotypes, $\mathrm{XX}, \mathrm{XY}$ and YY , where X is dominant over the Y allele. The number of each genotype in the population is as follows, $\mathrm{XX}=1185$, $\mathrm{XY}=3045$ and $\mathrm{YY}=1300$ individuals. Consider that there is random mating, no gene flow, no mutation and selection, and the population size is sufficiently large. The correct statement is

• A

  The population is in Hardy-Weinberg equilibrium and will remain the same if random mating is allowed for one generation.
• Correct answer
  B

  The population is not in Hardy-Weinberg equilibrium but will come to equilibrium if random mating is allowed for one generation.
• C

  The population is in Hardy-Weinberg equilibrium and will deviate from equilibrium if selection is acting against any one genotype.
• D

  The population is not in Hardy-Weinberg equilibrium and will come to equilibrium if selection is acting against the dominant genotype.

Hence, the correct answer is option: 'B'.
