In which condition the gene ratio remains constant for any species?

1. Sexual selection

2. Random mating

3. Mutation

4. Gene flow

Which of the following would lead to deviation from Hardy-Weinberg equilibrium?

1. Random mating

2. Lack of mutations

3. No gene flow or gene migration

4. Natural selection

In Hardy- Weinberg equation, the frequency of heterozygous individual is represented by

(1) P²

(2) 2pq

(3) pq

(4) q²

A population will not exist in Hardy-Weinberg equilibrium if

1. individuals mate selectively

2. there are no mutations

3. there is no migration

4. the population is large

In a population of 1000 individuals 360 belongs to genotype AA, 480 to Aa and the

remaining 160 to aa. Based on this data, the frequency of allele A in the population is

1. 0.4

2. 0.5

3. 0.6

4. 0.7
