is there a lethal gene?

[MarkS]

I am also now very confused. If a spider and pinstripe combo is lethal then how do you get a spinner blast. I was told that a spider bred to a pin stripe is a spinner, then the spinner to a pastel will give you a spinner blast, which is what i have. am i correct or is the breeding sequence wrong. I am new to snake genetics.

It's not. The person writing that was either mistaken or they're comments were taken the wrong way. This thread IS over 6 years old and more info is now known.

Spider X Spider breeding is suspected of being lethal since no known homozygous spiders exist. Pinstripes on the other hand are fine, Pinstripe X Pinstripe has been produced but the homozygous pinstripe looks like any other pinstripe. Woma X Woma will produce a homozygous woma which is an all white snake which unfortunatly will not live longer then a day or two. I also believe that Sable has been proven now to have some issues, as a live spider X sable has never been produced. They seem to die in the egg full term. Also homozygous Sables seem to have the same type of neurological issues that spiders have (spinning and twisting head quavers) I believe there are also issues with breeding Champagnes to other morphs but I can't remember off hand what those are right now.


Yup, I just checked WOBP morph list and it says that champagne x spiders hatch but don't live very long.
