Final answer:
Ovoviparity refers to the development of an embryo within the female with nourishment derived from a yolk.
Step-by-step explanation:
In ovoviparity, fertilized eggs are retained in the female, but the embryo obtains its nourishment from the egg's yolk and the young are fully developed when they hatch. This occurs in some fish, sharks, lizards, snakes, vipers, and invertebrate animals.
