Question

Consider the following statements with reference to female reproductive system :
Statement 1 : The presence or absence of hymen is not a reliable indicator of virginity or sexual experience.
Statement 2 : The sex of the foetus is determined by the father not by the mother.
Choose the correct option from the following :

• A. Both the Statement 1 and Statement 2 are wrong.
• B. Statement 1 is correct and Statement 2 is wrong.
• C. Both the Statement 1 and Statement 2 are correct.
• D. Statement 1 is wrong and Statement 2 is correct.

Answer 1

The Correct Option is C

Statement 1: The hymen is a thin membrane that can stretch or tear for various reasons, such as physical activity, menstruation, or injury. Therefore, the presence or absence of the hymen is not a reliable indicator of virginity or sexual experience.

Statement 2: The sex of the fetus is determined by the father (via the sperm carrying either an X or a Y chromosome). The mother always contributes an X chromosome, so it is the father’s contribution (X or Y) that determines whether the child is female (XX) or male (XY).

The correct answer is (C) : Both the Statement 1 and Statement 2 are correct.

Answer 2

The correct answer is: (C) Both the Statement 1 and Statement 2 are correct.

Let's analyze both statements in the context of the female reproductive system:

• Statement 1: "The presence or absence of hymen is not a reliable indicator of virginity or sexual experience."

  This statement is correct. The hymen is a thin membrane located at the opening of the vagina, but its presence or absence cannot be used to determine virginity or sexual experience. It can be stretched or torn due to various reasons, such as physical activity, tampon use, or medical examinations, and is not necessarily linked to sexual intercourse.

• Statement 2: "The sex of the foetus is determined by the father not by the mother."

  This statement is also correct. The sex of the fetus is determined by the combination of sex chromosomes from both parents. The mother contributes an X chromosome, while the father contributes either an X or a Y chromosome. If the father contributes an X chromosome, the baby will be female (XX), and if the father contributes a Y chromosome, the baby will be male (XY). Therefore, the father's contribution determines the sex of the fetus.

Therefore, both statements are correct, making (C) Both the Statement 1 and Statement 2 are correct the correct option.
