Calico's - Any lethal combos to stay away from?

[C&H Exotic Morphs]

don't get mad. lol if i'm wrong and you're attending daytona i'll gladly buy you a beer. it's not complicated when it comes to what i'm trying to say in regards to allele inheritance. i've never heard of proteins or modifiers restricting an allele from being inherited. do you have any studies or links to theories about this? and even if so, why would you cling to that and be so against the homozygous form being lethal? why would you think that would be more probable than a lethal homozygous, which we've actually seen with other genes? i'm not trying to be rude. i tried to agree to disagree earlier, but when you kept pressing and asking me questions, i answered. i'm not the only one with these views. people with much more knowledge than i will ever have share the same opinions.

again, i can agree to disagree. can you?

I wasn't mad it's all good.
I can definitely agree to disagree.

A couple things I found.
First was eye color in humans and how if 2 people with blue eyes have a baby on occasion they will have a baby with brown eyes. This is because there is other genetic material and genes involved.

Also the whole Banana/Coral Glow sex determination and how/why it works the way it does is more than enough proof that we don't really know much about the genetics of these animals besides the phenotypes that we are playing with.
