Answer 2

• The sperm of the father determines whether the baby would be a boy or girl.
• Men and women both have sex chromosomes.
• One X and one Y chromosome are found in men, while women have two X chromosomes.
• This means that the egg will always have an X chromosome, whereas the sperm can have both the X and Y chromosome.
• The fertilization is during which the sperm fertilizes with the egg.
• If the sperm with an X chromosome fertilizes with an egg, a girl is born.
• If the sperm with a Y chromosome fertilizes with an egg, a boy is born.
• Hence, there is always a fifty percent probability of whether a boy or girl is born.
