Question

Select the incorrect statement among the following.

विकल्प

• p² + 2pq + q² = 1. This is the binomial expansion of (p + q)².

• When frequency measured differs from the expected values, the difference (direction) indicates the extent of evolutionary change.

• Hardy-Weinberg principle says that phenotype frequencies in a population are stable and are constant from generation to generation.

• The gene pool (total genes and their alleles in a population) remains constant. This is called genetic equilibrium. Sum total of all the allelic frequencies is 1.

Answer 1

Hardy-Weinberg principle says that phenotype frequencies in a population are stable and are constant from generation to generation.

Explanation:

Hardy-Weinberg principle states that allele and genotype frequencies remain constant, not phenotype frequencies. Phenotypes can change due to environment and dominance effects.
