By Roger Highfield for the Daily Telegraph- Sat 27 Jan, 2007- from an article reporting on the discovery of the Monitor lizard’s ability to
procreate without a mate.

"...The genetics of this type of parthenogenesis in lizards means that all her hatchlings would have to be male. These would grow up to mate with their own mother and therefore, within one generation, there would potentially be a population able to reproduce sexually on the new island."


If a human virgin birth could occur, Jesus should have been a girl, not a boy, because all his genes must have come from Mary. She would only have the genetic wherewithal - in humans, a bundle of genes called the X chromosome - to make a female.


Not so for the Komodo. Sex determination is analogous to that of mammals, the difference being that the lizard's sex chromosomes are W and Z and it is the males, not females (as with humans) which have two of the same type of sex chromosome while the females are have one W and one Z. Thus with parthenogenesis, each egg only gets half of the mother's genetic material (that is a W or a Z chromosome, but not both) so only females are produced.
