  multiplication of the same parts by a simple process of growth […] may be called homogenesis [... and] is found not only in plants, but in animals

• 2) The ordinary form of sexual reproduction, in which the offspring resembles the parent and passes through the same course of development. (OED 2011)
  category alternation of generations

  It has now been proved [...]  that in plants, and in numerous animals, the successive generations are not alike; that from one generation there proceeds another whose members differ more or less in structure from their parents; that these produce others like themselves, or like their parents, or like neither; but that eventually, the original form reappears. Instead of there being, as in the cases most familiar to us, a constant recurrence of the same form, there is a cyclical recurrence of the same form. These two distinct processes of multiplication, may be aptly termed homogenesis and heterogenesis
