The way I remember what a codominate trait is is through highschool biology talking about human traits: If a curly haired and a straight haired person has children, they have wavy hair. Ta-da! Anything else with hair gets weird, but that one's straight forward usually. I think if two wavy-haired people have kids they'd be one curly, one straight, two wavy. That's always been the best, easiest examply of codominate traits I've heard. Kind of like a simplified eye-color chart is good for dominate and recessive, and hetero/homozygous. I have blue eyes so I'm homozygous recessive. My father has blue eyes, by mother has brown. By brother has brown, and he has to be a heterzygote because of the homozygous recessive father.

That's all the genetics I can explain, becuase after that I start going cross-eyed. I keep beardies because they're sweet, and while they're lovely critters I'm not worried about WHY they're pretty. Or about making prettier babies. I may dabble later, but I'll need a refresher course in genetics and I'll probably just breed guppies instead (they're so easy!)
