Select the correct statement from among the following.

Correct option is A

The correct answer is (A) A child who inherits an X chromosome from the father will be a girl.

Explanation:
• In humans, sex is determined by the sex chromosomes. Females have XX and males have XY.
• The mother always contributes an X chromosome. Therefore, the sex of the child is determined by the father.
• If the father contributes an X chromosome, the child will be a girl (XX).

Information Booster:
• If the father contributes a Y chromosome, the child will be a boy (XY).
• Humans have a total of 46 chromosomes (23 pairs), out of which 1 pair is the sex chromosome.

Additional Knowledge:
• Both X and Y chromosomes have the same size (Option B): Incorrect, the X chromosome is significantly larger than the Y chromosome.
• Y chromosome is shorter than X chromosome (Option D): While factually true, Option A directly and fully addresses the fundamental rule of human sex determination generally tested in this context.
