I'm hoping someone can explain this.. because I've been trying to understand it. In snakes I've seen the whole % chance of a normal looking animal being het for something.. but why do snakes only have this percent of a chance whereas other reptiles.. IE leopard geckos, are fully Het or Homozygous for that trait if 2 hets were bred together? I don't quite get the why of snakes not being the same. Any help on that would be appreciated.

1.1 Columbian Redtail Boa (BCI)(Sutekh and Isis)
2.2 Leopard geckos (2 Blizzards (Caine and Goliath), 1 het Blizzard (Lilith) and 1 Tangerine Albino (Tequila Sunrise ...Tiki for short))
0.1 Savannah Monitor (Kiros)
13 rats
5 Gerbils
2 Dogs (Loki and Storm)
2 cats (Sahara and Hercules)

Check this out: Leopard Gecko Genetics

Most known snake morphs are simple recessive genes like albinism in geckos.

Side effects may include paralysis
and death but are generally mild.

I'm reposting the link because it wouldn't work for me when I clicked on it. It's pretty good as far as it goes, though I disagree somewhat with the definition of heterozygous.

I haven't looked at more than the one leopard gecko genetics web site. FWIW, heterozygous for a recessive mutant mated to heterozygous for a recessive mutant produces
1/4 homozygous normal (two normal genes)
2/4 heterozygous for the recessive mutant (one normal gene paired with one gene for the recessive mutant)
1/4 homozygous for the recessive mutant (two genes for the recessive mutant)

And that is true for leopard geckos, snakes, mice, fruit flies, corn, etc.

Examples: Albino ball pythons

Breed a known heterozygous albino ball python with a normal ball python and their offspring have a 50% chance of being heterozygotes for albinism.

Breed two known heterozygous albino ball pythons with one another and (statistically speaking of course) 25% of the offspring will be albino. The remaining offspring will appear normal. However, each of these normal-looking individuals will have a 2/3 (or "66%" chance of being heterozygotes for albinism.
