Answer:

A. XYY

Step-by-step explanation:

Nondisjunction: The term "nondisjunction" is described as the failure of "sister chromatids" or "homologous chromosomes" to separate properly or precisely during cell division.

Gynandromorphism hasn't been discovered or identified in human beings, but it has been expressed or found in a variety of other creatures. However, a few scientists believe that gynandromorphs are considered as chimeras.

Example: In insects, the given condition can be caused due to the fact that two distinct sperm enters in one egg.
