Final answer:
Reptiles have three main reproductive patterns: ovipary, ovovivipary, and vivipary.
Step-by-step explanation:
Types of Reproductive Patterns in Reptiles
There are three types of reproductive patterns found in reptiles: ovipary, ovovivipary, and vivipary.
Ovipary:
Ovipary is the most common reproductive pattern among reptiles. It involves the development of an embryo within an egg outside the mother's body. The eggs are laid on land and undergo incubation until they hatch. Examples of reptiles that reproduce through ovipary include turtles and most snakes.
Ovovivipary:
Ovovivipary is a reproductive pattern where the eggs develop and hatch within the mother's body. However, there is no direct connection between the mother and the developing embryo. The offspring receive nutrients from the yolk sac until they are ready to hatch. Examples of reptiles that reproduce through ovoviviparous include some species of snakes and lizards.
Vivipary:
Vivipary is a reproductive pattern where the offspring are born alive, without going through an external egg stage. The embryos develop inside the mother's body and receive nutrients directly from her. Examples of reptiles that reproduce through vivipary include some species of skinks and garter snakes.
