The Coccidae can, and mainly do, breed asexually (parthenogenetically).
The individual is the product of sexual reproduction; a person is an individual of lower rank, which may be produced asexually.
- As is the case with the Oligochaeta, the Polychaeta furnish examples of species which multiply asexually by budding.
This genus also propagates asexually, like Ctenodrilus, which may possibly belong to the same family.
This fact gave rise in ancient times to the false idea that the tapeworm originated from the union of these segments; and in modern times it has led to the view that the tapeworm is not a segmented organism (the monozoic view), but is a colony composed of the scolex which arises from the embryo and of the proglottides, which are asexually produced buds that, upon or before attaining their full size and maturity, become separated, grow, and, in some cases, live freely for a time, just as the segments of a strobilating jelly-fish grow, separate and become sexual individuals (the polyzoic view).
