Detailed explanation-1: -A few plants, reptiles and fish are also capable of reproducing in this manner. A few organisms such as crayfish, snakes, komodo dragons and sharks can reproduce sexually as well as by parthenogenesis. This is known as facultative parthenogenesis.

Detailed explanation-2: -3.2 Parthenogenesis True parthenogenesis (Greek for “virgin birth”) is a form of asexual reproduction in which the production of offspring occurs in the absence of any male genetic contribution. Females produce unfertilized eggs that will develop into viable embryos (Neaves and Baumann, 2011).

Detailed explanation-3: -The lizards are all female and parthenogenetic, meaning their eggs develop into embryos without fertilization.

Detailed explanation-4: -Parthenogenesis is a form of asexual reproduction by self-impregnation resulting in the production of a zygote from an unfertilized egg. Thus, it is also referred to by many as “virgin birth”. Parthenogenesis takes place in both asexual animals and plants. In animals, the embryo develops from an unfertilized egg.

Detailed explanation-5: -Parthenogenesis occurs in invertebrates such as water fleas, rotifers, aphids, stick insects, and ants, wasps, and bees. Ants, bees, and wasps use parthenogenesis to produce haploid males (drones). The diploid females (workers and queens) are the result of a fertilized egg.
