Question

How many types of gametes are produced during oogenesis in human females?

Options

• One type carrying Y

• One type carrying X

• Four different types of gametes

• Two types: one carrying X and one carrying Y

Answer 1

During oogenesis in human females (XX), only one type of gamete is produced: eggs carrying the X chromosome. Since females lack the Y chromosome, they cannot produce Y-bearing gametes. All eggs produced are genetically identical with respect to sex chromosomes.
