During meiosis, individuals with the male XX genotype occur when the SRY gene located on the Y chromosomes shifts to the X chromosome with the crossing ovary. It is not possible for these individuals to have children. Abnormal but benign growth(gynecomastia) in the amount of breast tissue is very likely to occur in men due to an imbalance of the hormones estrogen and testosterone.
A similar condition in women is Swyer Syndrome (XY-woman). Because the production of testosterone hormone is partially or completely blocked in people with Swyer Syndrome(XY-female), these people are genetically male and female in image. Sex-determining region on the Y chromosome of people with Swyer syndrome called Partial of Y is shorter than normal and this brevity SRY-Gene encoded by the testis-determining factor of the hormone testosterone hormone production, which leads to incorrect masculine, which provides the appearance of the Buddha causes it to be partially or completely blocked the production of. The XY-woman is not distinguished much from the XX woman in image. Although they have a large clitoris, uterus and vagina, they do not have ovaries. The incidence of XY-female in society is 1:3000. 98% of embryos with Swyer syndrome die in the womb in the first month of pregnancy.
