Genetics question for the experienced...

Conserving_herps Oct 18, 2006 09:03 AM

Back in 2005, I purchased a male honduran from Terry Dunham and it's an albino possible het hypo possible het anery (and 25% chance of being a hybino). Next season in 2007, depending on his weight, I might be able to test breed it to see if 1) it is definite het anery and 2) if it is definite het hypo or even a hybino.

Now, I have 2 proven female breeders...one is a ghost and one is a zero tipping vanishing hypo.

Ok, so if on the first pairing of the said male with the ghost female, I know that if I get a ghost hatchling, that ghost hatchling will be 100% def het albino and the parent male will be proven to be definite het anery AND a definite het hypo. But I still wanted to prove that it could be a hybino. I know for certainty that if I get a 'wild-type' looking hatchling, then it is not a hybino. But if I do not get a 'wild-type' looking hatchling even if I get a ghost or a hypo, it still does not prove that the parent male is a hybino.

Which brings me to my second test breeding... breeding the subject male parent (which is an albino possible het hypo possible het anery (and 25% chance of being a hybino). If I breed him to my zero tipping hypo female for this 2nd test pairing this spring...and, if ALL the offsprings are hypos, then the male parent could be a hybino (just a "could be" and not definite). The only way I will know that it is not a hybino is if they produce some 'wild-type' hatchlings.

The conclusion I am getting here is if the 2 test breed pairings above do not produce any 'wild types' then, it is just with greater certainty and odds on my favor that the male parent is a hybino (but not 100% sure). And if any one of the females produces any wild type, then it is 100% sure that it is not a hybino.

I just wanted to test if the albino looking male is in fact a hybino and not just het hypo. My main question after all this reading (and I truly appreciate your patience !!! )is ... Is there any other genotype of female I can be testing this male with to prove whether or not he is a hybino?

I maybe overlooking something here and any input would be great.

Picture below was when he was just about 6 months old back in March and he is much bigger now.

Thanks,

Ray

That all sounds about right. The only way to "prove" its a hybino would be many many breedings with hypos. A single wild type proves its not, but as the number of hypo offspring goes up with out the apperance of single wt the possibility that it is a hybino goes up.

I think that you would be OK calling it a hybino if it produced if it produced something like 10 or 15 hypos and no wild types. (the odds of that are like 1 in 11000 or so.

I also hope that it proves out to be a hybino het anery for you. That would be very cool.

Best,

As you mentioned before, if producing 10-15 hypos without a wildtype is having odds of 1:11000 or so, that's a pretty good bet to say it's a hybino...but a lot of work still has to be done. Actually, I will be happy if the ghost female partner to be would be able to produce a ghost...and that would surely make the male albino definite het for anery and for hypo (even if not sure if it's a hybino). That ghost hatchling would be definite het albino.

Thanks again for your response.
