How parthenogenesis works in snakes
Unlike humans, where women have two sex chromosomes of the same type (XX) and men have two different (XY), in snakes it's the female that has the different combination (ZW) while the male has two the same (ZZ).
During normal egg production in any species, the number of chromosomes is divided in two, because during sexual reproduction half of the genetic material for the offspring comes from the male sperm. In humans this means that all eggs contain one X-chromosome, whereas in snakes, egg-cells can contain one Z- or one W-chromosome.
In parthenogenesis the genome must be duplicated to achieve the full complement of chromosomes without any input from a male.
In previous cases in snakes, single W- and Z- egg-cells were doubling up to form either WW eggs (an invalid and therefore infertile combination) or ZZ eggs, which were viable and by definition male.
The Artis python seems to be first doubling her chromosomes to ZWZW – then going through the division process to produce viable ZW embryos which are females and identical clones of herself. This happens in about only 40% of her eggs.

Your right, it is a worthy discussion to post. Also noticed, not many ball python posts are marked as Hot Topics.
