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

The tendency of population to remain in genetic equilibrium may be disturbed by 

1. random mating

2. lack of migration 

3. lack of mutations

4. lack of random mating

At a particular locus, frequency of 'A' allele is 0.6 and that of 'a' is 0.4. What would be the frequency of heterozygotes in a randomly mating population of equilibrium ?

(1) 0.16

(2) 0.36

(3) 0.48

(4) 0.24

Hardy-Weinberg's principle of 'zero evolution' is based on

(1) genetic equilibrium

(2) random mating

(3) no migrations

(4) All of the above

If the population of a place has a certain character which is recessive in as many as 100 individuals. Find the value of q if total number of individuals are 1000

If 900 people make a population such that 300 are albino. Calculate the frequency of carriers?
