I have come across a snake that looks like a bull snake/rattle snake cross breed. Just want to know is it possible? Thanks

No it is not possible. The two do not even belong to the same family. (Besides first is oviparous and second ovoviviparous).
Crossbreeds are possible within the same genus.

As Petra said, the cross-breeding of these two genera is not possible. If you cannot post the photo, try e-mailing it to any of us who have responded. Perhaps we can i.d. it for you. You may want to mention locality data. That is always helpful.

Don't get too specific with your definitions of what can or can not interbreed. Animals from different genera certainly do interbreed occasionally, such as woma pythons (Aspidites) and carpet pythons (Morelia). However, the offspring are very likely to be infertile. That being said, the differences in reproduction between viviparous snakes and oviparous snakes would likely create a barrier none could cross.

That, Mr. D., may well be proof that the "splitters" overdid things on that group of Australian snakes.

Breeding between 2 different kinds of python (no matter how different they are) is not the same as 2 snakes from different families (Crotaline and Colubridae even though colubrids are a very poorly defined group of snakes). There is no way in hell it could happen IMO though nature does have a funny habit of making us look stupid in what we think can and can not happen.. Basicly a bullsnake breeding with a rattlesnake would be the same as a human breeding with a chimp, if you beleive in evolution that is (please dont turn this into an eveolution vs religion debate). That is about how close they are.
As for the confusion, P.c.sayi (bullsnakes)do everything in their power to make you think they are a buzzworm. Their threat stance is remarkably similar, they buzz their tail violently and flatten their body and head. In the SW part of bullsnakes range (southern NM specificly) they even share a similar overall coloration. There C.atrox was the primary Crotalus found (atleast near White sands were I used to live)and they had an almost redish look to them. The bullsnakes in that area were also redish shareing a remarkably similar overall coloration and pattern. Back then even i was confused from time to time (I was all of 11 and hadnt been edumcated properly yet LOL)untill the bullsnakes would start hissing. Though crotalus can hiss from time to time it is hardly comparable to the loudness of the genus Pituophis which have probaly the loudest vocal ability of any snake on the planet. If you could hear a hiss over the shaking of the tail it was definately a bullsnake.
Basicly, you saw one or the other, probaly a bullsnake if their was any confusion. If you could share a pic that would be great.

Melissa, if you can get that photo from your cell phone into your computer, you can easily upload it here to your "Profile" photo. That way we could have a look at the snake you have found. Also, let us know what area of the country you are in.
We also have a "Snakes for Identification" section in our Photo Album here, but that will take longer, as the uploaded photo has to be approved by a site manager.
Best Regards JohnZ

I don't think it's too big of a stretch to say that Aspidites and Morelia are pretty distinctive genera. Heck, the good folks over at NERD (who produced the woma x carpets to which I referred earlier) also bred a ball to a woma and produced offspring - which they so aptly call the "Wall." So even if you make the argument that Morelia and Aspidites may be close enough based at least on geographic isolation during their evolutionary paths...I don't think the same argument could be made for African Python and Aspidites.
And Jeremy, humans and chimps share about 99.5% of the same DNA, so I'd venture a guess that indeed we could produce offspring. Considering the amount of time both we and chimps have been on the planet in our current forms, we're probably far more closely related than even some members of the Viperidae family.
Anyway, just so my points are not lost, I'm by no means arguing that it is possible for a rattlesnake and a bullsnake to hybridize. It is, almost without a doubt, not possible.
