Variation in gene frequencies within populations can occur by chance rather than by natural selection. 
This is referred to as:

1. Genetic drift

2. Random mating

3. Genetic load

4. Genetic flow

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

(1) P²

(2) 2pq

(3) pq

(4) q²

If frequency of 'A' allele is 0.4 than, find out the frequency of 'B' allele and heterozygous genotype in a random mating population at equilibria.

1. 0.6 an 0.24

2. 0.6 and 0.96

3. 0.6 and 0.48

4. 0.6 and 0.50

In a population, homozygous & heterozygous individuals are in a certain proportion. This proportion can't be changed by

1. Natural Selection

2. Mutation

3. Recombination

4. Use and Disuse of organs

According to Hardy - weinberg principle, the frequency of homozygous recessive (aa) individuals in a population is denoted by

1. $p^2$

2. 2pq

3. $q^2$

4. p + q

Hardy-Weinberg equation is used to check

1. Size of population 

2. Whether evolution is occuring in a population or not

3. Average lifespan of a population

4. Maximum life expectancy of a population

What will be the frequency of homozygote dominant in a population of triploid organisms.

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

Which one of the following would cause the Hardy-Weinberg principle to be inaccurate?

Hardy-Weinberg equilibrium can be disrupted by presence of all except

1. Genetic drift

2. Random mating

3. Non-random mating

4. Mutations
