How parthenogenesis works
Nettet31. aug. 2024 · So how does parthenogenesis work? Normally, animals that reproduce sexually combine egg and sperm cells. But in parthenogenesis, the egg cell combines with a “polar cell.” This cell contains a duplicate of an egg’s DNA. Lacking a male partner, females can use the polar cell to fertilize an egg. NettetThe reason parthenogenesis results in Males in the komodo dragon and females in whiptails has to do with sex chromosomes and sexual determination, and not the …
