oviparity: egg is produced, fertilized, then oviposited outside the female.

ovoviviparity: eggs develop normally and are fertilized, but are retained in female's reproductive tract until they hatch.

viviparity: eggs begin to develop, but lack enough yolk for complete development & often lack a chorion - embryos retained inside mother, receive nourishment after development has begun.

parthenogenesis: development without fertilization

polyembryony: one egg is laid in the host, clones itself & can produce from a few to 1,500 offspring.
