Speaking of Sonorans, one of them that hatched this year has VERY little dark pigment. We've never had hypo Sonorans, so I'm not sure what they typically look like as hatchlings, but from the adults I've seen, I don't imagine that they usually look quite like this. The parents were an amel and a het. The het is 25% possible het for snow, but I don't know of any hypo genetics in either. Any input?

The male parent of the het(so, the pictured hatchling's "grandpa" was het for snow.

Actually it would be 50%; the het came from a normal het for snow male and an albino female. It carries the albino gene for sure, but there's only a 50% chance it could carry the anery gene as well. I will illustrate:

Using M to indicate normal melanin presence and m for amel and E for normal erythros and e for anery, the male is MmEe(normal het for both ie het for snow). The female is mmEE(amel not het for anery). The possible contributions to offspring are illustrated in the attached image.

The MmEE's are normals het for amel, MmEe are normal het for snow, mmEE are amel het for nothing, and the mmEe are amel het for snow. Thus a normal colored hatchling is equally likely to be het for amel or het for snow.

I understand genetics and thats why I was asking about the 25%?I know if its less than a 50%chance of being het for a simple recessive then we don't even mention it,

btw,het for snow is acually the wrong term.It would be dbl-het for snow?

Well, it's a double het in the sense that it is het for two traits, but the term "double het for snow" seems odd since we usually refer to "snow" as its own color variety, even though it's actually a combination of two. "Double het for amel&anery" is probably best.

for dbl-het for snow,ghost,hybino,etc..........

its all good though.

would be lets say hypo het albino.If it shows one gene and is het for two others then it would be lets say hypo dble het for snow (anery and albino).

Now if its normal in apearrance and het for three traits its a triple het,

I see sometimes were people will say its a albino triple het?It would have to be a albino and carry three more simple recessive genes?It should be its a albino and is dbl-het for?

anyways,
