Researchers at the University of Texas at Arlington and research institutes in China and Myanmar studied flowerpot snakes to see how parthenogenesis works in these reptiles. (Alexander Murray ...

This species reproduces by parthenogenesis - a form of reproduction where embryos develop directly from an egg with no need for fertilization - and is responsible for the most severe envenomation ...

Fertilization is the fusion of two haploid gametes, during the process of sexual reproduction, to initiate the development of a new diploid organism with mixed genetical heritage. In flowering ...
