The correct Answer is:
To analyze the assertion and reason provided in the question, we can break down the information step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Mother should not be blamed for the birth of girls in the family." This implies that the gender of the child is not the mother's fault, and she should not be held responsible for having female children. 2. **Understanding the Reason**: - The reason given is "Father is responsible for the sex of the child." This indicates that the father’s genetic contribution determines the sex of the child. 3. **Genetic Basis of Sex Determination**: - In humans, sex determination is based on the combination of sex chromosomes contributed by both parents. The mother contributes an X chromosome (as she has XX chromosomes), while the father can contribute either an X or a Y chromosome (as he has XY chromosomes). - If the sperm carrying an X chromosome fertilizes the egg (which also carries an X), the resulting child will be female (XX). If the sperm carrying a Y chromosome fertilizes the egg, the child will be male (XY). 4. **Conclusion on Assertion and Reason**: - Since the father’s sperm determines whether the child will be male or female, it is accurate to say that the mother should not be blamed for the birth of girls. Therefore, both the assertion and the reason are true. - Moreover, the reason provided (that the father is responsible for the sex of the child) correctly explains the assertion. 5. **Final Answer**: - The correct option is **Option A**, which states that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
