Mack Snow Rainwater Snake Eyes

[delu]

Hi all,
The offspring below on the pics has snake eyes... but the parents doesnt have the eclipse morph (Rainwater and Mack Snow rainwater). I suspect.
is it possible that it is a mutation or is it always the eclipse morph which is responsible for the snake eyes?
And would you say that the offspring is a typhoon or a mack snow eclipse?

thanks and regards

Sorry I'm not sure what your question is?

I understand his question (correct me if I'm wrong!) He's saying that he bred two geckos he knows (for sure?) don't hold the eclipse gene but this offspring seems to have snake eye. He's asking if he's encountered a random mutation or if there's another reason for the way the geckos eyes look.

If the parents are het for eclipse they wouldn't look like eclipse but they would have a 25% chance of producing offspring with eclipse eyes. Are you sure they don't carry the gene? Can you ask the breeder you got the parents from if there is a chance they could be het eclipse?

yes, the parents dont take the eclipse gene. i asked both breeder already and they never had snake eyes in there breeding and never breed with eclipse...
but it is possible that the eclipse gene transmits for 3 or 4 generations?

Yes its possible for the trait to be hidden as a recessive het until the 3rd or 4th or 10th generation. If one parent is het for eclipse there is a 50% chance the offspring will be het for eclipse in each generation. I would assume both your parents are hets but the only way to prove it for sure it to breed one of the parents to a gecko that is eclipse and see if the offspring are also eclipse from that pairing. Potentially, you could breed that baby back to mom or dad and see that way too (approximately 50% of offspring should be eclipse if you do). However, that might not 100% rule out a mutation - even though I think it being a mutation is highly unlikely.

thanks a lot for your great comment. i will see next year if she is a real mack snow typhoon.
