Out of 23 pairs of chromosomes only two pairs are called sex chromosom...
Understanding Chromosomes
In humans, the total number of chromosomes is 46, organized into 23 pairs. These pairs are categorized into two main types: autosomes and sex chromosomes.
Types of Chromosomes
- Autosomes: Out of the 23 pairs, 22 pairs are autosomes. These chromosomes are the same in both males and females and carry the majority of genetic information related to body functions, growth, and development.
- Sex Chromosomes: The remaining pair, the 23rd pair, consists of sex chromosomes. In humans, these are designated as XX for females and XY for males.
Key Points
- There are 23 pairs of chromosomes in total.
- Among these, 22 pairs are autosomes and only 1 pair is sex chromosomes.
- Therefore, stating that "only two pairs are called sex chromosomes" is incorrect.
Conclusion
The correct answer is False. In the human chromosome structure, there is only one pair of sex chromosomes out of the total 23 pairs. This distinction is crucial for understanding genetic inheritance and the differences between male and female organisms.
