What is in q2 Hardy Weinberg equilibrium?
Correct answer: C. Frequency of the homozygous recessive genotype
- A. Frequency of the dominant allele
- B. Frequency of the recessive allele
- C. Frequency of the homozygous recessive genotype
- D. Number of both alleles
Explanation
In Hardy-Weinberg equilibrium, the equation p² + 2pq + q² = 1 is used to describe the distribution of genotypes in a population. Here, p² represents the frequency of the homozygous dominant genotype, 2pq represents the frequency of the heterozygous genotype, and q² represents the frequency of the homozygous recessive genotype. Thus, the correct interpretation of q² is the frequency of individuals with the homozygous recessive genotype. Other options are incorrect because they misinterpret q² as relating to allele frequency or the number of alleles, rather than the specific genotype frequency it represents.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
