Female Snake Gives Birth without a Male Companion

  • For the second time in two years, a captive snake has given birth without any interaction with a member of the opposite sex.
  • As per Jeff Briggler, virgin births are rare but can occur in some species through a process called parthenogenesis. It occurs in some insects, fish, amphibians, birds and reptiles, including some snakes, but not mammals.
  • Parthenogenesis is a type of asexual reproduction in which offspring develop from unfertilized eggs, meaning there is no genetic contribution by a male. It’s caused when cells known as polar bodies, which are produced with an animal’s egg and usually die, behave like sperm and fuse with the egg, triggering cell division.
