Mitosis/Meiosis
In contrast to the large X chromosome, the Y chromosome contains only 26 genes. Thus the zygote has 46 chromosomes, and when the zygote undergoes mitosis to begin to form an embryo , each cell will have the normal number of 46 chromosomes. It is important to remember that sex and gender have two separate definitions and many cultures include more labels than simply "male" and "female" to identify others.
