Five factors are known to affect Hardy- Weinberg equilibrium. Three of them are : gene migration or gene flow, genetic drift and mutation . Rest two are

Options

A. Somatic variation and natural selection
B. Genetic recombination and random breeding
C. Genetic recombination and natural selection
D. Lack of random breeding and Saltation

Answer

To solve the question regarding the five factors that affect Hardy-Weinberg equilibrium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hardy-Weinberg Equilibrium**:
- Hardy-Weinberg equilibrium is a principle in population genetics that states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences.

2. **Identify the Three Given Factors**:
- The question states that three factors affecting Hardy-Weinberg equilibrium are:
- Gene migration (gene flow)
- Genetic drift
- Mutation

3. **Determine the Remaining Two Factors**:
- We need to identify the other two factors that affect the Hardy-Weinberg equilibrium. These are:
- **Genetic recombination**: This refers to the process by which genetic material is physically mixed during meiosis, leading to new combinations of alleles.
- **Natural selection**: This is the process where organisms better adapted to their environment tend to survive and produce more offspring.

4. **List All Five Factors**:
- Now, we can compile all five factors that affect Hardy-Weinberg equilibrium:
- Gene migration (gene flow)
- Genetic drift
- Mutation
- Genetic recombination
- Natural selection

5. **Evaluate the Options**:
- The question may provide multiple-choice options. We need to identify which option lists genetic recombination and natural selection as the remaining two factors.

### Conclusion:
The five factors affecting Hardy-Weinberg equilibrium are:
1. Gene migration (gene flow)
2. Genetic drift
3. Mutation
4. Genetic recombination
5. Natural selection
