Sexi Spy (wallpapers): The members of many species of living things are divided into two or more categories called sexes (or loosely speaking, genders). These refer to complementary groups that combine genetic material in order to reproduce, a process called sexual reproduction / copulation. Typically, a species will have two sexes: male and female. The female sex is defined as the one which produces the larger gamete (i.e., reproductive cell) and which bears the offspring. The categories of sex are, therefore, reflective of the reproductive functions that an individual is capable of performing at some point during its life cycle, and not of the mating types, which genetically can be more than two.
