And because we're dealing with this abnormal X cell, we have two X chromosomes, two identical X chromosomes. And so because these two identical X chromosomes fuse with the sperm cell that contains the Y chromosome, we see that the genotype, the carriotype, will be XXY. And so this Zygold will eventually form an individual and that individual is said to have the XXY carriotype, which is also known as Clinfelter's syndrome. Now, what are some of the symptoms of individuals that have the syndrome? Well, because they have that Y chromosome, these will be males. Now, they will be unusually told and because of that additional X chromosome they're going to have female like breasts.
