In human sperm besides autosomes the chromosomes complement contains

Options

A. X andY
B. Either X or Y
C. Y only
D. X only

Answer

To solve the question "In human sperm besides autosomes the chromosomes complement contains," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Chromosome Types**:
- Humans have two types of chromosomes: autosomes and sex chromosomes.
- Autosomes are the chromosomes that do not determine sex, while sex chromosomes are responsible for determining the sex of an individual.

2. **Identify the Number of Chromosomes in Human Sperm**:
- Human sperm cells are haploid, meaning they contain half the number of chromosomes found in diploid cells.
- Humans have a total of 46 chromosomes (23 pairs), so sperm cells contain 23 chromosomes.

3. **Break Down the Chromosome Composition**:
- Out of the 23 chromosomes in human sperm, 22 are autosomes (non-sex chromosomes).
- The remaining chromosome is a sex chromosome, which can either be an X or a Y chromosome.

4. **Determine the Possible Sex Chromosomes**:
- In human males, sperm can carry either an X chromosome or a Y chromosome.
- Therefore, the sex chromosome in human sperm is not fixed; it can be either X or Y.

5. **Conclusion**:
- The correct answer to the question is that in human sperm, besides autosomes, the chromosome complement contains either an X or a Y chromosome.

### Final Answer:
The chromosome complement in human sperm, besides autosomes, contains either X or Y.
