Life cycle. Most lizards reproduce by laying eggs. In some small species, the number of eggs is rather uniform for each laying or clutch. ... A clutch of four to eight eggs may be considered typical, but large lizards such as the iguanas may lay 50 or more eggs at one time.

How do lizards reproduce sexually?

During sexual reproduction, a sperm and an egg combine to form a fetus. For that to work, each parent supplies half the genetic material. So in female lizards that reproduce sexually, chromosomes — the packages that contain DNA — are duplicated inside cells, and then undergo two rounds of cell division.

Are lizards asexual reproduction?

Without females, lizards in the Aspidoscelis genus, like this New Mexico Whiptail (Aspidoscelis neomexicana), reproduce asexually. ... The lizards are all female and parthenogenetic, meaning their eggs develop into embryos without fertilization.
