The phrase (from recollection) is parthenogenic, it's rare for it to happen, more so in snakes compared to things like Komodo dragons.
I think we've had a fairly in depth discussion about it in the past, it's interesting stuff.
Really? Wow I pictured it to be more common in snakes than in some lizards. That's cool I should have a dig round for it, although I probably won't understand it but its fascinating to know that kind of stuff. |

I dont know am afraid, Kates not a vet, shes a veterinary haematologist!
Oooh, info for you!
They have 36 chromosomes, in 18 pairs.
Apparently the question you have been asked is far more complicated than than a simple answer.
but again, apparently the answer is (haploid) = n, and (diploid) = 2n.
all sex cells are haploid, and all other cells in the body are diploid, except in plants.
Basically to put it bluntly I would say the question you have been asked is more how many chromosomes are in the haploid and diploid cells in a snake (and 4 other species).
Therefore there are 36 chromosomes in a corn snakes diploid cells and 18 chromosomes in a corn snakes hapolid cells. |

Diploids are like (if I remember correctly) are a double set of chromosomes, in humans it's 46 I think. Haploids... it's hard to describe... its the name given to a pair of diploids thin so in Humans, 23.
Have you found out the sex chromosomes give to snakes or don't you need to know that? |

Right well animals I'd chose would be;
Corn snake.
Dog (Jack russel as youv'e got one!)
Tortoise (Again! )
Think of some other 2;
I've done GCSE biology, never heard of diploids though.. |

I don't know specificity corns but most snakes have I think 32 -40 diploids, 36 being more common. As for haploids, I asked my b/f and he has no idea and I don't either! I think contacting a herp vet might be a good idea or I think Mike's OH is a vet, she might know.
