Question

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The Correct Option is A

To solve the problem, we need to determine how many types of sex chromosomes are present in the ova (gametes) produced by a woman.

1. Understanding Human Sex Chromosomes:
Humans have two types of sex chromosomes: X and Y.
- Females have two X chromosomes (XX).
- Males have one X and one Y chromosome (XY).

2. Gamete Formation in Females:
During meiosis (gamete formation), each ovum (egg cell) receives only one sex chromosome.
Since females have only X chromosomes, all ova will carry only the X chromosome.

3. Types of Sex Chromosomes in Ova:
Only one type of sex chromosome (X) is present in the ova produced by women.

Final Answer:
The ova produced by a woman contains \( ({1}) \) type of sex chromosome.
