When is blue not really blue?

[ConcinusMan]

Thank you very much! I like to throw ideas out there especially when I know I'm probably wrong. What pleases me even more is when somebody speaks up and tells me so!

Your response is what I've been fishing for Udo.

I need clarification though. When you say "there must be no yellow or green in the pattern" are you referring to axanthic in reptiles/amphibians?

I'm also confused about the human reference. I happen to have been born with some genetic quirks myself. All through my childhood my hair was the color of a new copper penny. As teen, my hair was mostly blonde. To this day, I still sunburn in about 30 minutes give or take, depending on latitude and time of year. My mustache and beard are still very red, and I still freckle. You said that redhead is yellow haired and that's what confuses me. Don't even get me started on my eyes. My eye color is hazel, but they sometimes look very blue. (Co-dominant inheritance, blue eyes, brown eyes)

I hear that red hair is an endangered genetic trait these days, as are green eyes. Both being recessive.

Are saying I'm hyperxanthic? What did you call me?



In spite of all this, both my parents are half native American. One is half Cherokee, the other is half Blackfoot. I inherited my red hair and fair skin from my father's mother I guess. She was a red haired fair skinned woman. My father is dark hair, dark skin, tans easily like his father.

So now this has turned into, "when is red hair fair skin, hazel eyes, a person with native American blood?"

But seriously, I want to learn more about the snakes and me.

yes

That´s what yourself pointed out before yellow (carotins) can turn to red by high density. Furthermore I would call you an albino!

Like most humans are albinos of different types, but those real complete
peoples native in Africa.
Back to the topic I would recommend to search for "Fancy Guppy Breeding genetics". Fisch colour is more like snake colour than mammal colour and Poecilia reticulata might be the best explored specy on earth.
