Genome represents total number of gene in

Options

A. A chromosome
B. Homologous chromosomes pair
C. Haploid set of chromosomes
D. Diploid set of chromosomes

Answer

To solve the question "Genome represents total number of genes in," we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Term "Genome":**
- The genome refers to the complete set of genetic material present in an organism. It includes all of the genes and non-coding sequences of DNA.

2. **Analyzing the Options:**
- **Option 1: Chromosome**
- A chromosome is a structure that contains DNA and proteins. It is not the total number of genes but rather a physical entity that carries genes.

- **Option 2: Homologous Chromosome Pair**
- Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same genes at the same loci but may have different alleles. This option does not represent the total number of genes in the entire genome.

- **Option 3: Haploid Set of Chromosomes**
- The haploid set of chromosomes (represented as "N") consists of a single set of chromosomes, which contains one copy of each gene. This is often referred to as the genome in organisms that reproduce sexually.

- **Option 4: Diploid Set of Chromosomes**
- The diploid set of chromosomes (represented as "2N") contains two sets of chromosomes (one from each parent). While it contains more genetic material, the term "genome" is typically used to refer to the haploid set in the context of counting genes.

3. **Conclusion:**
- The correct answer is **Option 3: Haploid Set of Chromosomes**, as the genome represents the total number of genes in a haploid set of chromosomes.

### Final Answer:
The genome represents the total number of genes in the **haploid set of chromosomes** (Option 3).
