humans sex gametes each have the haploid number of chromosomes(23) compared to a normal cell. when the sperm feritilises the egg, the number is doubled to form the full cell. the 23rd pair of the chromosome is the one that determines th sex of the foetus. if it is a "XX" chromosome, it will be a girl and if its a "XY" chromosome, it will be a boy.

By the sex determining region (SRY) on the Y chromosome.

XX is female

XY is male

The default sex in humans us female. At about eight weeks into gestation the SRY, a control gene, turns on if a Y chromosome is in the fetus and then several processes take place to " make " a male. The position of the SRY is the important point as some males, very rarely, are XX, as the SRY has migrated to the X chromosome.

The sex of humans is determined by the sex chromosomes given by the child's father. When the sperm fertilizes the egg it is either carrying a X or Y chromosome. For the sex to be female it has two X chromosomes, and a male it is an X and Y. So when the sperm divides it either carries one X or one Y while the mother's eggs all carry an X.

HE has the chromosomes of a male and female, therefore he determines if it will become a male or female. This is also why some males can only have females.

By the male. A female does not have the chromosome for a male (the Y chromosome); a male has both X and Y chromosomes.

If there is doubt (after birth) and the external organs don't give the answer, a DNA test will be done. A boy will have sex chromosomes X and Y while a girl will have X and X.
