Directions: In the following questions, a statement of assertion (A) ...
Sex of a child is dependent on the type of the male gamete that fuses with the female gamete. Human beings possess 23 pairs of chromosomes. Out of these, 22 pairs are known as autosomes, while the remaining one pair comprises sex chromosomes (XX in females and XY in males). At the time of fertilisation, the egg cell fuses with the sperm cell, resulting in the formation of the zygote. If the egg cell carrying an X chromosome fuses with the sperm carrying an X chromosome, the resulting child would be a girl. If the egg cell carrying an X chromosome fuses with the sperm carrying a Y chromosome, the resulting child would be a boy.

Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Role of Males in Determining Sex
- In humans, the male's genetic contribution is crucial in determining the sex of the child.
- Males carry both X and Y chromosomes (XY), while females carry two X chromosomes (XX).
Reason (R): Males and X Chromosomes
- The reason states that males have two X chromosomes, which is incorrect.
- Males actually have one X and one Y chromosome, which is essential for sex determination.
Analysis of the Statements
- Assertion (A) is true because the sex of the child is indeed determined by the male's sperm, which can carry either an X or a Y chromosome.
- Reason (R) is false as it incorrectly states that males possess two X chromosomes.
Conclusion
- The correct choice is option 'C': Assertion (A) is true but reason (R) is false.
- Understanding the chromosomal basis of sex determination is vital in genetics, and this question illustrates a common misconception regarding male chromosomal composition.
Key Takeaway
- Males (XY) can contribute either an X or Y chromosome, thus influencing the sex of their offspring, while the claim about two X chromosomes in males is erroneous.
- In humans, the male's genetic contribution is crucial in determining the sex of the child.
- Males carry both X and Y chromosomes (XY), while females carry two X chromosomes (XX).
