Q. How is reproduction done in beings of the class Reptilia?

These beings reproduce sexually through internal fecundation by means of copulation between female and male individuals. They lay eggs with shell and extraembryonic membranes. The embryo thus develops outside the mother's body and within the egg (there are also ovoviviparous reptiles that retain the egg within the body until hatching).
