Chromosome complement of human male is

Options

A. 44+AO
B. 44A+XX
C. 44A+XY
D. 44A+XXY

Answer

To determine the chromosome complement of a human male, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Total Number of Chromosomes**:
- Humans typically have a total of 46 chromosomes.

2. **Identify the Chromosome Pairs**:
- These 46 chromosomes are organized into 23 pairs.

3. **Differentiate Between Autosomes and Sex Chromosomes**:
- Out of the 23 pairs, 22 pairs are called autosomes, which are the same in both males and females.
- The 23rd pair consists of sex chromosomes, which determine the sex of the individual.

4. **Determine the Sex Chromosomes in Males**:
- In human males, the sex chromosomes are represented as XY. This means that one chromosome is an X chromosome and the other is a Y chromosome.

5. **Summarize the Chromosome Composition**:
- Therefore, the chromosome complement of a human male can be summarized as:
- 44 autosomes (22 pairs) + 1 X chromosome + 1 Y chromosome.

6. **Final Answer**:
- The chromosome complement of a human male is 46 chromosomes, comprising 44 autosomes and 2 sex chromosomes (XY).
