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?
1. The size of the population is very large.
2. Individuals mate with one another at random.
3. Natural selection is present.
4. There is no source of new copies of alleles from outside the population.

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

1. Genetic drift

2. Random mating

3. Non-random mating

4. Mutations
