Document Summary
Individual"s genetic sex begins with sex chromosomes inherited from two parents. Mothers provide x chromosome to all offspring, fathers determine the sex by providing either another x (female) or a y (male) Turner syndrome: only one x chromosome (xo) - lack of second sex chromosome impacts fetility, growth, hormone production and is associated with higher risk of diabetes, osteoporosis, and cardiovascular disease. Normal female genitalia but ovaries develop abnormally. Klinefelter syndrome: xxy genotype - individuals are male but they usually experience reduced fertility and require hormone treatment at puberty to promote the development of secondary male sex characteristics. Associated with normal intelligence, perhaps marked by mild cognitive difficulties and social awkwardness. Xyy genotype: boys appear to be physically within typical limits but tend to be taller and leaner, suffer from acne, higher risk for minor physical abnormalities. Men with this genotype are fertile, but slightly more likely to produce sperm with sex chromosome abnormalities.
