Total collection of genes at any time in a population is
Or
The sum total of all the genes in a population is called

Options

A. genome
B. gene pool
C. germplasm
D. gene bank

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the total collection of genes in a population at any given time.

2. **Evaluating Options**: We have four options to consider:
- Option 1: Genome
- Option 2: Gene Pool
- Option 3: Germplasm
- Option 4: Gene Bank

3. **Analyzing Option 1 (Genome)**: The term "genome" refers to the complete set of DNA, including all of its genes, in an organism. However, it is specific to an individual organism rather than a population.

4. **Analyzing Option 2 (Gene Pool)**: The "gene pool" is defined as the total collection of genes and their alleles in a population at a given time. This term is widely used in population genetics and is the correct answer to the question.

5. **Analyzing Option 3 (Germplasm)**: "Germplasm" refers to the genetic material of plants and is often used in the context of plant breeding. It does not refer to the total gene collection of a population.

6. **Analyzing Option 4 (Gene Bank)**: A "gene bank" is a facility that stores genetic material, such as seeds or DNA, for future use. It is not a term that describes the total collection of genes in a population.

7. **Conclusion**: After evaluating all options, the correct answer is Option 2: Gene Pool, as it accurately describes the total collection of genes in a population.

**Final Answer**: The total collection of genes at any time in a population is called the **Gene Pool**.
