Question

Which of the following is true according to Hardy-Weinberg principle ?

• A. The allele frequencies in a population are stable and is constant from generation to generation.
• B. Five factors are known to affect Hardy-Weinberg equilibrium -gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection.
• C. Sum total of all the allelic frequencies is 1.
• D. All of the above.

Answer 1

The correct option is D All of the above.

According to the Hardy-Weinberg principle, the allele frequencies in a population are stable and is constant from generation to generation in the absence of other evolutionary influences like gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection.

This is called genetic equilibrium. Sum total of all the allelic frequencies is 1.

It is represented by, $p^2+2pq+q^2$= 1
