In organisms showing sexuality, the gametes are of two types: male and female. They may be produced in special organs (e.g. carpel and anther in angiosperms, archegonia and antheridia in lower plants and some algae). The gametes may be derived from the same parent AUTOGAMY0 or from two different parents
