Reproduction can occur through one parent (asexual) or through two parents (sexual).
Further, some sexual reproducing organisms may contain both sexes in one (e.g. earthworm), i.e. they can be bisexual, or the sexes may be separate (e.g. humans), i.e. they are unisexual.
Thus, it may be concluded that unisexual and bisexual modes are subtypes of sexual reproduction.
But broadly, the reproduction is classified into sexual and asexual types only.
