A haploid set of all the genes present in a gamete is called

Options

A. Genotype
B. Phenotype
C. Genome
D. Linkage group

Answer

To solve the question, "A haploid set of all the genes present in a gamete is called," we will analyze the options provided and arrive at the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Haploid**: Refers to a single set of chromosomes (n), which is characteristic of gametes (sperm and egg cells).
- **Gamete**: A reproductive cell that carries half the genetic information of an organism.

2. **Identifying the Options**:
- The options given are:
- A) Genotype
- B) Phenotype
- C) Genome
- D) Linkage group

3. **Analyzing Each Option**:
- **Option A: Genotype**: This refers to the genetic constitution of an individual for a specific trait or set of traits. It does not represent the entire set of genes in a gamete. Thus, it is incorrect.
- **Option B: Phenotype**: This refers to the observable physical characteristics of an organism, which result from the interaction of its genotype with the environment. It does not pertain to the genetic makeup itself, so it is also incorrect.
- **Option C: Genome**: This term refers to the complete set of genes or genetic material present in an organism. In the context of gametes, it would specifically refer to the haploid genome, which is indeed the correct term for the haploid set of all genes in a gamete.
- **Option D: Linkage group**: This refers to a group of genes that are inherited together due to their proximity on a chromosome. It does not represent the complete set of genes in a gamete, making it incorrect.

4. **Conclusion**:
- After analyzing all the options, the correct answer to the question is **C) Genome**. A haploid set of all the genes present in a gamete is referred to as the genome.

### Final Answer:
**C) Genome**
