Genetic Odds

Ok I have some questions these may sound stupid so forgive me in advance.

Soo ok I paired my SHTCT's together, and the babies I can expect to be hypo tang, ct, maybe even a baldy? I'm just wondering what might be % rate of getting each type of babies? I bought the herpers genetics book but haven't started reading it yet, I WILL SOON! lol

Another question I have and I will ask me vet about as well, I have a tremper albino the last rescue I got. Well he has webbed toes on one foot and also seems so small body wise, I got him and another hatchling SHTCTB the same week from a breeder but the S has grown much faster than him, is there some kind of test I can get done to see if he has some sorta genetic problem like a growing deviancy? If he did what would cause that? I don't want to breed him I just worried about him I plan on keeping him fully as a pet no matter what the outcome. He eats very well and is getting a nice fat tail but body wise doesn't seem to be growing at a normal rate, I hope this makes sense.

For first part of your post, its impossible to give a percentage... The SHTCT morph is a combination of three polygentic traits (hypomelanism, tangerine, carrot tail). Since you are breeding togeather SHTCT X SHTCT then you should pretty much get SHTCTs. Some will be more hypo than others, some will be more tangerine, some will have more carroting... but as for a % of each grade of hypo-ness and % of carroting there is no answer in advance. Baldies are SHTCTs that have been linebred to the point where their head has completely hypoed out as well.

As for a genetic test, I doubt there is one. There is really no incentive for science to map out the genome of leopard geckos right now and everything that we know about their genetics is from watching breeding outcomes between different visible traits. The albino you have might have its problems due to inconsistant incubation temps, genetics, or embryotic damage caused by factors such as egg rotation, the mothers diet, the mothers age, damaged sperm, etc.

Thank you so much for the info!

I was told today there was no sure fire way of testing him for problems that could be genetic, which I wasn't sure but figured there wasn't. I will be keeping him as a pet reguardless, and he had a fecal taken in today along with 2 others so hopefully they come back all clear. I was going to take him in but since he is eating, pooing and doing everything normally I figured I would wait on that.

Also thanks for the genetic help to I dunno what I would do without this place and it's members i'd be lost I suppose :main_yes:.
