The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Chromosomes**: Human cells typically contain 23 pairs of chromosomes, making a total of 46 chromosomes. These chromosomes are categorized into two main types: autosomes and sex chromosomes. 2. **Identifying Autosomes**: Out of the 23 pairs, 22 pairs are known as autosomes. Autosomes are chromosomes that do not determine the sex of an individual. They carry genes for various traits unrelated to sex. 3. **Identifying the 23rd Pair**: The 23rd pair of chromosomes is different from the other 22 pairs. This pair is responsible for determining the sex of an individual. 4. **Naming the 23rd Pair**: The 23rd pair consists of sex chromosomes, which are referred to as heterosomes. In males, this pair is represented as XY, while in females, it is represented as XX. 5. **Conclusion**: Therefore, the 23rd pair of human chromosomes is known as heterosomes, which are also referred to as sex chromosomes or allosomes. **Final Answer**: The 23rd pair of human chromosomes are known as heterosomes. ---
