Sex differences in humans

difference between males and females

Sex differences in humans have been studied in a variety of fields. Sex determination generally occurs by the presence or absence of a Y in the 23rd pair of chromosomes in the human genome. Phenotypic sex refers to an individual's sex as determined by their internal and external genitalia and expression of secondary sex characteristics.

Man does, woman is
  —Robert Graves

Sex differences generally refer to traits that are sexually dimorphic. A subset of such differences is hypothesized to be the product of the evolutionary process of sexual selection.
