In sperm cell four we lack any sex chromosome and in sperm cell three we basically have two identical Y chromosomes. Now, if we take a normal Xcel that contains a single X chromosome, and that normal Xcel combines with this abnormal sperm cell number four, then what happens is the Zygo that is formed will only have a single sex chromosome, the X chromosome, because there is no Y chromosome within this particular sperm cell. And this is what we mean by the Xokaryotype, also known as Turner's Syndrome. So when a normal X cell combines with the anuplooid sperm cell number four the Zygote will contain an Xocaryotype and that Zygote will eventually develop into individual that is said to have Turner's syndrome. Now, what are some of the symptoms of this particular syndrome? Well, notice that because we don't have a Y chromosome and the Y chromosome is needed to develop that male individual these individuals with Turner syndrome basically develop into females.
