Genetics isn't always as neat & prescribed as a chart in a biology text. Sure, there is the dominant/recessive thing going on with some traits, where parents displaying dominant traits may have a certain percentage of children showing recessive ones. But then there are other traits where the genes are more blended, sort of. It's been a while since I studied that in school, so I can't explain it more precisely. But it's the reason for redheads and hazel eye color in humans, and medium-sized chickens when bantams & standard-sized birds mate. And Ma Nature works it out so that a large chick doesn't develop inside a bantam-sized egg, & vice-versa.
I have a handsome mid-sized roo whose father was my Brown Leghorn & mother was a bantam.
