Does the male goat or the female determine the sex of the baby goat?

The sex of a baby goat, like many mammals, is determined by the male goat (buck). Male goats carry both X and Y chromosomes, while female goats (does) only carry X chromosomes. If the sperm carrying an X chromosome fertilizes the egg, a female kid is produced; if the sperm carrying a Y chromosome fertilizes the egg, a male kid is produced. Therefore, it is the male that ultimately determines the sex of the offspring.
