Document Summary

Chapter 5 gender identity and gender roles. Gender: psychological sense of being female or male, influenced by socially ascribed roles, it is based partly on anatomy, partly on psychology of individual and partly on culture and tradition. 23 chromosomes from each parent combine, the 23rd pair is the sex chromosomes, ovum carries x, and sperm carries either x or y (female: xx, male: xy) Embryo: stage of prenatal development that begins with implantation of fertilized ovum and ends with development of major organ system at 2 months after conception. At 7th week after conception, the xx or xy code begins to cause changes in the gonads and genitals, the y chromosomes causes the testes to differentiate, and in the absence of y, ovaries begin to differentiate. Rare embryos that only have one x chromosome instead of xx or xy become female. Ovaries begin to form at 11 or 12 weeks.
