What chromosome determines the sex of a child?
The sex chromosomes determine the sex of an organism. In humans, it is the 23 pair. Females pass on either or their X chromosomes, while males pass on either their X or their Y. If the male passes on their X chromosome, the resulting offspring is female. If they pass on their Y chromosome, the resulting offspring is male.
