Answer 1

Explanation:

Both Male(XY) and female (XX) will form gametes.

Male form two types of gamete one is X and other is Y and female will also form two gamete but of same type i.e X and X.

So 1 will be X, 2 will be Y.

Now when the fusion of gametes takes place two X and Y gametes will form male offspring and two X and X chromosome will form female offspring.

Thus 3 will be XX(female), 4 will be XY(male) , 5 will be XX(female)and 6 will be XY(male).
