Transfer of genes from one gene pool to another is called :

Options

A. gene flow
B. mutation
C. speciation
D. genetic drift

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the transfer of genes from one gene pool to another. This involves the movement of genetic material between populations.

2. **Identifying the Options**: The options provided are:
- Option 1: Gene flow
- Option 2: Mutation
- Option 3: Speciation
- Option 4: Genetic drift

3. **Analyzing Each Option**:
- **Option 1: Gene flow**: This refers to the transfer of genetic material (alleles) between populations. It occurs when individuals from one population migrate to another and breed, introducing new genes into the gene pool.
- **Option 2: Mutation**: This is a change in the DNA sequence of an organism. It does not involve the transfer of genes between populations; rather, it is a source of new genetic variation within a population.
- **Option 3: Speciation**: This is the process by which new species arise. It does not directly refer to gene transfer but rather to the evolutionary process that leads to the formation of new species.
- **Option 4: Genetic drift**: This is a mechanism of evolution that refers to random changes in allele frequencies in a population. It does not involve the transfer of genes between different populations.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 1: Gene flow**. This term specifically describes the transfer of genes between populations.

5. **Final Answer**: The transfer of genes from one gene pool to another is called **Gene flow**.
