Gen. Question???

Hi everyone. I bought 3 leopard geckos 1 year ago to show them in an aquarium. But I start reading about Leos and they are very interesting animals.

My question is:

By breeding a Male Leucistic (Patternless) with a female Blizzard, what I can get?

I heard before that you can get something called: Banana Blizzards, is that true? Or I will get just normals?

Thank you very much everyone!!!

You would get all normals that are double het(heterogeneous) for banana blizzard. If you were then to breed the offspring together you would in thery get 1/16 normal, 2/16 het blizzard, 3/16 blizzard 2 het patternless, 2/16 het patternless, 4/16 doulbe het, 3/16 patternless 2 het blizzard, and 1/16 banana blizzard. Hope this helps.

Bryan!......you just gave me an instant headache!

By the way, "Kid Rock" (tangs name) Is doing great!

It is hard to make Banna Blizzard and most of them are just Hi Yellow Blizzard..... Yes you will make some double hets and the Blizzard line are hard to get their "genes" to be compitle with other ressivce genes.... Similar to Blazin Blizzard and Banna Blizzard due I only know one that are true genetic Banana Blizzard.

Bryan, cool gecko. Thank you very much for your help. Everything sounds very interesting, where did you guys learned all this genetic formulas over /16? Bryan how do you predict this statistics?

Sorry for my ignorance, I will like to learn about this....

has a good site, you may have to search these forums for which traits are dom and which are co-dom. You can convert the % it gives you into a fraction fairly easily. Does anyone have a full list of the morphs with genetic info?

That would be the wonderous punnet square!!!...lol Although as Preston said, with bannana blizzards it doesn't seem to work out properly (something else must be affecting the genes). Basically to make a punnet square you assign letters to the traits (MUST be simple recessive or dominant traits for it to work!). For blizzard I'd use B as the normal allele, and b as the recessive (blizzard) allele....for patternless I'd use P for the normal allele and p for the recessive (patternless) allele. If you are crossing double hets then you have BbPp x BbPp. From that you make all possible combinations of letters from each parent's genotype to make up their gametes (the alleles that will end up in their eggs or sperm). In this case both parents will have the combinations of BP, Bp, bP, and bp...from there you make a square!...lol I'll attempt to show you how to set up the box...lol

.......BP.....Bp.....bP.....bp
BP..BBPP..BBPp..BbPP..BbPp
Bp..BBPp..BBpp..BbPp..Bbpp
bP..BbPP..BbPp..bbPP..bbPp
bp..BbPp..Bbpp..bbPp..bbpp

Added:
I have a morphs page on my site (the link is in my sig), that describes all the different morphs I could come up with (pretty complete list) and does have the genetic info there (dominant/recessive/linebred). I may have a few things off...but it should be pretty good. I also went over the whole punnet square thing there too and how to breed the morphs.

Thanks that is exactly what I was looking for!

Here are some sites that have some genetic info. They are not specific to geckos but genetics is all the same once you determine the form of inheritance. nerd

Overton, glad the tang is doing well.

it's kind of limiting, but this is a good little tool.
