78 views

Genetics play a crucial role in determining if you'll have a boy or girl. Your baby's gender is determined by the sperm from the father, which carries either an X or Y chromosome. An X chromosome from the father pairs with the mother's X chromosome to produce a girl (XX), whereas a Y chromosome from the father pairs with the mother's X chromosome to produce a boy (XY).

FAQs & Answers

  1. What chromosomes determine a boy or girl? A boy is determined by the presence of a Y chromosome (XY), while a girl is determined by two X chromosomes (XX).
  2. Can diet affect my baby's gender? While there's no conclusive evidence, some studies suggest diet and timing of conception may have minimal effects on the likelihood of having a boy or girl.
  3. Is there a way to select a baby's gender? Gender selection is possible through methods like IVF and preimplantation genetic testing, though ethical considerations vary.
