Virgin Corn Laid Fertile Eggs!
I have a ghost corn female that I kept seperate as she was not eating very well and regurgitated a lot. As a result she took rather long to grow. In breeding season I noticed that she looked gravid but didn't worry too much as I knew she had never been with other snakes, let alone a male - since she was a hatchling. However, she went on to lay 8 fertile eggs that all hatched! The babies were all perfect but all were strange and unusual colours (beautiful colouring). None of them were ghost corns though. Has anybody else experienced anything like this? Furthermore, she was only 18 months when she laid and I would never have paired her up anyway. We've had a couple of young snakes lay infertile eggs without having been mated, but to have a virgin snake have 8 fertile eggs - that is wierd? I'd be very grateful for any ideas?
Many thanks, Chantel (SOUTH AFRICA) |
Snakes are known to reproduce parthenogenetically. I believe the most famous example is a burmese python in a zoo in Europe, but quite a few hot keepers have had their crotalids give birth to young without ever having been mated.

Hm... if the offspring were weird colors, then I think we'd all like to see photos of them... :) But yes, an odd and rare occurance, not something I've heard of second hand before, let alone witnessed... (but something I have read of in books as having happened once or twice before).

I too would like to see some pics of the wierd colores offspring...j/c :)

As someone else pointed out, if a ghost were to fertilize herself, all the offspring should be ghosts (or I would think other things in addition to hypo/anery, such as ghost motleys or snows or something). Definitely post pics if possible. :)
Also (if this were the case) since the female carries both Z and W chromosomes, should the offspring really be all females, or should there be a mix of males and females? Are there any details about the offspring of the burm that was mentioned? |
If this were in fact a true case of parthenogenesis, wouldn't all of the hatchlings be Ghosts?

You're absolutely correct. They should all be ghosts, and should all be females. Parthenogenesis is in reality a clone of the mother. The babies should not be recieving any other genes than the mothers, but who knows. |
There was an article in Reptiles magizine as well as reports on the web about the burmese. All of the offspring where the same as the mother right down to each and every scale.
Are you sure the mother wasn't with a male even for a short period? I have had snakes mate when being transported together for only 45 minutes. maybe put with another while cages where being cleaned ect? |
All of the offspring from the Burm were female.
