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. However, these females are sterile and that's because that second X sex chromosome is needed to actually fully develop the ovaries. And so these individuals are basically sterile because they do not have developed fully developed ovaries and fully developed female genitalium. Now let's move on to the final type of sex chromosome abnormality, the XYY.
