Both of them remove red. Somehow they prevent the snake's skin from making red pigment. And if the snake is heterozygous, enough of the necessary gene product (protein) gets made that the snake has the normal amount of red. But they have to prevent different steps in the red-making process, because a double het, het anery A & het anery B, is classic colored. So let's say there are 5 steps in the red-making process for discussion's sake, something like this:
Substance A is turned into B by protein a
Substance B is turned into C by protein b
Substance C is turned into D by protein c
Substance D is turned into E by protein d
Substance E is turned into red pigment by protein red maker
If Anery A is an animal that doesn't have any protein a and Anery B is an animal who doesn't have any protein b then the double heterozygote has 1/2 the normal level of a and 1/2 the level of b and looks normal because a low amount of a or b gets the job done. This means the genes for them are at different loci, maybe even on different chromosomes.
Hypo and strawberry are at the same locus and act on the same protein (we could call it h), so you can have a homozygous hypo snake or a hypo/strawberry or a homozygous strawberry. Amel & ultra, same thing, you can have amels, ultras or ultramels.
Just keep in mind I made up the A, B, C, D etc, I don't know what real geneticists are using as the symbols for corn snake color genetics.
LOL-thank you!!
Had to have my 21 year old explain it to me, but I sort of get it now.
