Question

In the XX–XO type, the male produces two kinds of gametes, which are:

Options

• A+X (gynosperm) and A+O (androsperm)

• A+Z and A+W

• A+X (androsperm) and A+O (gynosperm)

• A+X and A+Y

Answer 1

In the XX–XO type, the male (AA+XO) produces two kinds of gametes — A+X called gynosperm, and A+O called androsperm, which carries no sex chromosome. The female (AA+XX) produces only one kind of gamete with the X chromosome.
