« Sex » : différence entre les versions

In biology, '''sex''' refers to the categorization of organisms (or their parts) with regard to the role they play in reproduction.  When a species reproduces sexually, it usually does so by producing two types of gametes that have to come together to form a new member of the species.  One type of gamete is large and non-mobile (ova), whereas the other type is small and mobile (spermia).  When an organism or an organ produces large and non-mobile gametes, it's called '''female'''.  If it produces small and mobile gametes, it's called '''male'''.
