    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Okay for anyone who's produced or worked with hets and double hets what are your experiences with odds? I bred a male albino tremper het for patternless to a double het female (albinoXpatt) and the first clutch to hatch was two normal offspring. I was hoping for a single albino, or possibly a albino patternless. I know it's poss for two normals to appear in a clutch with the mother being double het but a bit dissappointed. So either percentage wise I missed out, or she isn't a double het. I have two more clutches waiting to hatch from her and I guess time will tell. Now my second question. I acquired a beautiful female tangerine leopard gecko a couple of weeks ago and she has never left her humid hide in her tank since I"ve had her. Any ideas? She is caged alone with a normal hide as well. Thanks.

I have a lot of DH's, mine ate Dh for albino and patternelss and so far all of the offspring appear to be normals but Ive only hatched out 5, I had a few bad eggs since they were all first timers and a lot more eggs cooking so I will post more as they hatch b ut I have been dissappointed with my DH matings too.

Now I h ave 1.2 1.o being normal het for albino and 0.2 that are jungle het for albino and all of the babies have been nice. No normals, some albino jungles, 2 stripes (1 normal 1 albino) and some normal jungles so Ive had much better results from them.

As for the hie issue, she may be coming out when you are alseep, I often see mine in the humid hide all day and they come out around 1 - 3 am and are alot of times still out when I get up at 6am to cook hubby breakfast. But I don't get much sleep so I get to see mine more active more times than some.
 
Sometimes probability doesn't cooperate. Last year I hatched nothing but rainwaters from a rainwater het patternless bred to a patternless rainwater albino. I was wondering if I got cheated on the female. This year, I've hatched four rainwaters and two PA's. Your ratios will get closer to those predicted by probability, with a larger sample (more hatches).

It can take leos awhile to settle in, especially older animals. Just give her time. Like Wendy said, she could be coming out when you're not around too.

Ken, if I read your question correctly here are your percentages.

Homozygous Tremper, Het. Patternless,
x
Het. Tremper, Het. Patternless,

12.5% Het. Tremper,
25% Het. Tremper, Het. Patternless,
12.5% Het. Tremper, Homozygous Patternless,
12.5% Homozygous Tremper,
25% Homozygous Tremper, Het. Patternless,
12.5% Homozygous Tremper, Homozygous Patternless,

As you can see with your pairing you only have a 12% chance to produce a Patternless Albino. The normal looking offspring could be het for Tremper albino, they could be het for patternless, or they could be het for both. They could also just be normals. They would have to be bred to know for sure.

Just wanted to add that the ones that hatch out to be Tremper albinos my or may not be het for patternless and the same for the ones that appear to patternless may or may not be het for Tremper. Again they would have to be bred to know for certain.

Hope I didn't confuse anyone or mess anything up.

Actually, Jeremy, I think your numbers and chart may be correct, but your text is incorrect. All of Ken's normal-looking geckos are het Tremper Albino, possible het patternless since the father was homozygous Albino. All offspring from this pairing will carry the Tremper gene.
 
Rob, you are absolutely correct. Confused myself thinking of 2 double hets. I'm working with a ton of those this year.
