Male XX and female XY sometime occur due to
A
deletion
B
transfer of segments in X and Y chromosome
C
aneuploidy
D
hormonal imbalance.
Answer
transfer of segments in X and Y chromosome
Explanation
Solution
Male XX and female XY sometimes occur due to transfer of segments in X and Y chromosomes. Deletion is the loss of an intercalary segment of a chromosome which is produced by a double break in the chromosomes followed by the union of remaining parts. Aneuploidy is a condition of having fewer or extra chromosomes than the normal genome number of the species.
