digenesis, dī-jen′e-sis, n. reproduction by two methods, a sexual followed by an assexual.
This phenomenon has been known by the name of alternate generation; we have called it digenesis.
There is alternation of form, on account of the double multiplication (digenesis) and migration through several individuals.
