Male \( X X \) and female \( X Y \) sometime such conditions occur due to

1. Deletion
2. Transfer of segments in \( x \) and \( Y \) chromosomes
3. Aneuploidy
4. Hormonal imbalance

Correct answer: Aneuploidy

Solution

A male with XX chromosomes or a female with XY chromosomes usually results from an abnormal number or combination of sex chromosomes, which is a form of aneuploidy. Deletions, segment transfers, or hormonal imbalance may affect sex development, but they do not by themselves explain the chromosomal sex reversal described here.
