50%/66% het RAPTORs...

Hey guys,

I've been doing a little thinking on Leopard Geckos who are listed as 50% het RAPTORs or 66% het RAPTORs. Here is what I'm talking about:

We'll start with the 50% case... To get a 50% het RAPTOR, one het RAPTOR must be bred to a gecko who does not have any RAPTOR in them. There are 3 Recessive traits in play, Eclipse, Albino, and Patternless Designer. For the hatchling to be het for an individual trait, there is a 50% chance. For the hatchling to be het for all 3 traits, there is a 6.25% chance, or 1/64 chance.

If you hatch Albinos who are 50% het RAPTOR, the odds increase a little bit. Since we have already taken care of the Albino portion, we are only trying to get 2 traits. Therefore, making it a 25% chance for het RAPTOR, 1/4.

Here is the breakdown for 66%... With the 66%, it is a Het RAPTOR x Het RAPTOR. Just like the 50%, we are trying to make the gecko het for 3 recessive traits, only this time, we have a 66% chance of achieving each one individually, or 2/3 shot. For the gecko to be het for all 3 traits, there is a 29% chance, or 2/7 (In Lowest Terms).

If we hatch out Albinos that are possible het for RAPTOR, the odds go up to 44% or (4/9) to be double het.

Now you might be asking yourself, how did he come up with all of this? Or you might be saying, he's crazy!

This all comes from probability. If you have a 1/4 chance at achieving each trait individually, to find out what the odds are of getting all three, simply multiple the ratio by itself 3 times, resulting in 1/64. The same thing works with the 2/3's chance, just multiple the ratio by itself for as many traits you are trying to make the gecko het for.


Sorry if this was a little confusing, it's something which I've been thinking about, and trying to accurately portray geckos on my site with.

Thank you for reading it,

can we say math wiz lol had to read it twice to make sense of it but that seems to be the case i would have never have been able to come up with that

1/2 x 1/2 x 1/2 = 1/8 (12.5%), although you are absoultey right that a het. RAPTOR x normal will not give "50% het RAPTORs" which seems to be a misunderstanding among some people.

The rest of your calculations seem correct, though, so I guess this was just an oversight. And I agree it is important to have at least a slight understanding of statistics when dealing with genetics like this.

Thanks CJ... I overlooked the 50% one. I appreciate it!

Well first of all most say het "Raptor" refering only to the fact the gecko carries the Eclipse trait. Especially if it is an Aptor-albino, of course. Second there is only one simple recessive trait involved, that is Albino.;) The patterning, and eye trait, are all linked together. I am pretty sure it is what is called a cooperating(or incomplete) recessive trait. The definitions are just confusing me still.:main_rolleyes:

The way I list mine is they are 100% het Albino, and are "het Eclipse". I have not had a "possible het" turn out to be a non-het from this project, and for me, it only reinforces my thinking that the patterns are responsible for the Eclipse trait. I have some of what should be 66% hets, but I just call them "probable hets".

If you remember the Patternless Stripe project, makes "Eclipse" geckos all on it`s own, or if you breed them to R/Aptors, and that is how we found out that the Patternless types are a "het". The funny thing is even the "het" for Aptor/Patternless Stripe geckos are "het" for Eclipse. Since it takes a combination of the patterning traits, to get a "Patternless" or Eclipse, you cannot be sure what pattern will pop out next, and they are more or less all "multi hets".

Even the very first release of "Aptors"(before there was a Raptor release) and "het Aptors" were "het" for Eclipse/Raptor, and Ron did not seem to have any idea, thinking it was a simple recessive. I was told, the ones I bought were an Aptor "possible het" Raptor, and a "het Aptor", that in no way was "het" for anything other than Aptor. I hatched Raptors from that pair, and noticed that all of my Aptor het Raptor`s babies ended up as "het Raptors" themselves.

That of course, was the reason I started thinking that it is the "Aptor" that was responsible for the "Eclipse" mutation, not another seperate gene. Basically all you need, is to have "het Aptors" to make your own Raptors, and that is the same way that the patterning traits seem to work.

Reverse Stripes are something like a "super" form of Stripes, and "Patternless Stripe/Designers", are like a "super" form of the stripes. Then we have the Eclipse gene which came from the "Patternless" type, in the same way.
