Document Summary
The biology of sex interacts with complex environmental influences to produce a male or female phenotype. Gender refers to social, learned, and personal aspects of sex. Mothers provide an x chromosome to all their offspring. Fathers determine the offspring"s sex by providing either another x (resulting in a female) or in a y chromosome (resulting in a eamale) Some individuals possess a mosaic karyotype: means that the individual has cells with differing complements of chromosomes (e. g. 45, x/ 46, xy/ 47, xyy) Abnormalities due to a third sex chromosome appear to have mild effects and thus many cases do not get diagnosed. Results when a child receives only a single x chromosome. Individuals can have typical female genitalia, but have abnormal development of ovaries, leading them to not produce either eggs or normal levels of female hormones, which leads to infertility.
