Let's take a het anery x DH snow breeding...
a normal baby from this breeding-
33% DH snow
25% het anery
12.5% het amel
~would the correct way to state this be:
33% DH snow
58% het anery
45.5% het amel
because in snow there are amel and anery???

Now a DH ghost x super salmon breeding...
25% salmon
25% salmon het ghost
25% super salmon het ghost
25% super salmon
~would the correct way to state this be:
50% super salmon
50% normal salmon
50% salmon het ghost
25% super salmon het ghost
25% normal salmon het ghost

I am just starting to understand genetics and am getting confused.

Thanks a lot,
Nicole

50% probability heterozygous albino, 66% probability anerythristic.

"Snow" is a slang term for the phenotype produced by a combination of albino and anerythristic genes. Since we are talking genotypes here, we use the names of the genes.

All the babies would be salmon (50% probability homozygous salmon, 50% probability heterozygous anerythristic). As I understand it from posts on this forum, some good-looking heterozygous salmons can be mistaken for homozygous salmons, and some poor homozygous salmons can be mistaken for heterozygous salmons. So the easiest thing to do is to lump them all together as salmons unless pedigree data or breeding tests determine which an individual snake is.

There is no such thing as a "normal salmon". Because a "normal" looks like the average boa constrictor found in Central America/Colombia. Which a salmon does not. Correct wording would be either "salmon" or "heterozygous salmon".

Been there. Fortunately, I had good teachers in my college genetics course and when I worked in the univ. genetics lab. Hope you've gotten yourself a genetics text. I've seen stuff on the web that confuses me, and I know what they are trying to say. Keep working on it, and keep asking questions. BTW, my old boss has a web page (http://www.ringneckdove.com) with some good stuff about genetics on it. None is snake related, and you will have to work up to some of it. But the principles are the same for boa constrictors and ringneck doves and mice and corn.
