Patient's question:
NoDoctor's answer:
Hello, it's not easy to determine. The gender of a child is determined by the combination of sperm and egg, and the final phenotype is the gene. The gender is decided by a pair of chromosomes in the fertilized egg. In females, the sex chromosomes are XX, while in males, they are XY. One chromosome comes from the father and the other from the mother. The probability of having a boy or a girl is 1:1.
