Document Summary

Sexual reproduction between two individuals increases variation in the gene pool: variation in the gene pool of a species enables quick evolutionary adaptations to changes in the environment, variation also corrects genetic errors and disadvantageous mutations. Prenatal sexual differentiation begins with the chromosomes: during an early stage of prenatal development, both male and female have a set of. Female mammal has two x chromosomes and a male has an x and a y. For the first 2-3 months of gestation, every single person was protofemale, meaning that everyone has the ability to develop either female or male reproductive structures. Sex and hormones (cont"d. : wolffian ducts are the precursors to other male reproductive organs, develop into the vas deferens and seminal vesicles, m llerian ducts are precursors to the female"s oviducts, uterus, and upper vagina. Females do not have the sry gene and their gonads develop into ovaries, the egg- producing organs.
