Explanation:
The sex of a human child is determined by the sex chromosomes inherited from the parents. A normal human female has two X chromosomes (XX), while a normal human male has one X and one Y chromosome (XY).
- Two X chromosomes: If the zygotic cell has two X chromosomes, it will develop into a normal human female child. This is because the presence of two X chromosomes triggers the development of female reproductive organs and characteristics.
- Only one Y chromosome: If the zygotic cell has only one Y chromosome, it will develop into a normal human male child. This is because the presence of a Y chromosome triggers the development of male reproductive organs and characteristics.
- Only one X chromosome: If the zygotic cell has only one X chromosome, it will develop into a female child with Turner syndrome. This condition is characterized by short stature, infertility, and other physical abnormalities.
- One X and one Y chromosome: If the zygotic cell has one X and one Y chromosome, it will develop into a normal human male child. This is because the Y chromosome contains the SRY gene, which triggers the development of male reproductive organs and characteristics.
Therefore, the correct option is A) Two X chromosomes.
