Understanding Human Sex Chromosomes
In humans, the determination of biological sex is primarily influenced by the composition of sex chromosomes. Let's break down the key aspects:
Sex Chromosome Composition
- Females (XX): Women have two X chromosomes, which are denoted as XX. This configuration is essential for typical female development and functions in reproduction.
- Males (XY): Men possess one X and one Y chromosome, represented as XY. The presence of the Y chromosome triggers male biological development and characteristics.
Significance of the Y Chromosome
- The Y chromosome carries genes that are critical for male sex determination and sperm production. One of the key genes on the Y chromosome is the SRY gene, which initiates the pathway for male sex differentiation.
Why Other Options are Incorrect
- Option A (Both males and females have two X chromosomes): This statement is false because only females have two X chromosomes. Males have one X and one Y.
- Option B (Males have two Y chromosomes): This is incorrect. Males have one Y chromosome, not two. Having two Y chromosomes is not viable in humans.
- Option D (Sex chromosomes do not affect sex determination): This statement is misleading. Sex chromosomes are crucial for determining biological sex in humans.
Conclusion
Thus, the correct answer is option 'C': Females have two X chromosomes (XX), and males have one X and one Y chromosome (XY). This chromosomal structure is fundamental to our understanding of human biology and reproduction.
