Haploid complement of chromososme of an organism is

Options

A. Genotype
B. Phenotype
C. Genome
D. Genetic system

Answer

To answer the question "Haploid complement of chromosome of an organism is," we need to analyze the options provided and identify the correct one. Here’s a step-by-step solution:

### Step 1: Understand the Term "Haploid"
- **Definition**: Haploid refers to a cell or organism that has a single set of chromosomes. In humans, for example, haploid cells are the sperm and egg cells, which contain 23 chromosomes.

### Step 2: Analyze the Options
1. **Genotype**: This term refers to the genetic makeup of an organism, which includes both alleles for each gene. It does not specifically refer to the haploid set of chromosomes.

2. **Phenotype**: This term describes the observable physical characteristics of an organism, which result from the interaction of its genotype with the environment. It does not pertain to the haploid chromosome set.

3. **Genome**: The genome is the complete set of DNA, including all of its genes. In the context of haploids, the genome refers to the total genetic information contained in a haploid cell (like a sperm or egg).

4. **Genetic System**: This term is broader and refers to the overall system of genetics within an organism, including all genetic interactions and processes. It does not specifically refer to the haploid chromosome set.

### Step 3: Identify the Correct Answer
- Based on the definitions and explanations, the correct answer is **Genome**. The haploid complement of chromosomes in an organism is represented by its genome, which includes all the genetic information in a single set of chromosomes.

### Conclusion
The haploid complement of chromosomes of an organism is best described by the term **Genome**.
