In our society women are balmed for producing female children. Choose the correct answer for the sex- determination in humans

Options

A. Due to some defect in the women
B. Due to some defect like aspemia in man
C. Due to the genetic make up of the particular sperm which fertilizes the egg
D. Due to the genetic make up of the egg

Answer

**Step-by-Step Solution:**

1. **Understanding Sex Determination in Humans:**
- In humans, sex determination is based on the combination of sex chromosomes contributed by the male and female gametes (sperm and egg).
- Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).

2. **Role of Female Gamete (Egg):**
- The female produces eggs, and all eggs carry one X chromosome. Therefore, the contribution from the female is always an X chromosome.

3. **Role of Male Gamete (Sperm):**
- The male produces sperm that can carry either an X chromosome or a Y chromosome.
- If a sperm carrying an X chromosome fertilizes the egg, the resulting child will be female (XX).
- If a sperm carrying a Y chromosome fertilizes the egg, the resulting child will be male (XY).

4. **Conclusion on Blame for Female Children:**
- Since the sex of the child is determined by the type of sperm (X or Y) that fertilizes the egg, it is incorrect to blame women for producing female children.
- The determination of whether a child is male or female is dependent on the genetic makeup of the sperm from the male.

5. **Correct Answer:**
- The correct answer is: "due to the genetic makeup of the particular sperm which fertilizes the egg."
