Answer 2

Answer:

• Human beings exhibit male heterogamy. In humans, males (XY) produce two different types of gametes, X and Y.
• The human female (XX) produces only one type of gametes containing X chromosomes.
• The sex of the baby is determined by the type of male gamete that fuses with the female gamete.
• If the fertilizing sperm contains X chromosome, then the baby produced will be a girl and if the fertilizing sperm contains Y chromosome, then the baby produced will be a boy.
• Hence, it is a matter of chance that determines the sex of a baby.
• There is an equal probability of the fertilizing sperm being an X or Y chromosome. Thus, it is the genetic makeup of the sperm that determines the sex of the baby.
