Solution

The correct option is A 2
The genotype given consists of one X chromosome with two genes and one Y chromosome. During gametogenesis, these two chromosomes will segregate. Hence, the gametes formed will be: one with the X chromosome and autosomes and second with the Y chromosome and autosomes.
So, the correct answer is '2'.
