The sex of your baby is tottally dependant upon the male's sperm, each sperm has a specific sex chromosome, either a Y or an X . every egg of a female has only X sex chromosomes. When one sperm conjoins with one egg, the female gives her X chromosome and the male gives the chromosome (either X or Y) belonging to the sperm that made it to the egg first and will determine the sex. XX = Female
XY = Male * All the things you hear about eating meat during your pregnancy will produce a boy and fruits will produce a girl are myth!
