    Lots of talking, but little logic. The reason whites exist is because God wished it so - simple as that. Got it?

    I knew a man of Irish/Black ancestry and he had very light brown skin with distinct yellowish brown eyes. His wife was strawberry blonde perhaps if they have children the negroid element will die off. He always kept his head shaved so I never saw whether it was curly or kinky and he was well spoken, hated rap, golfed, dressed in Polos and khakis and often made fun of one fully negroid student.

    Hetrozygous recessive genes do not manifest themselves in the phenotype. Homozygous recessive genes do. It is almost impossible to eliminate recessive genes in a population because they are carried in low frequency, even when actively being selected against. The reverse is not the case, however. Once recessive genes have a positive selective value, they quickly replace dominant genes which are inferior for that environment. For this reason, there is often talk of evolution being driven by recessive genes. This turns out to be an over simplification.

    "Recessive genes or dominant genes" as we are discussing them above, are in reality, two alternate forms of at a single gene site, in other words two alleles. Most things we can see in individuals, height, eye or hair color, intelligence, etc. are not the result of one gene site. They are polygenetic, meaning that there are several gene sites involved. Height, for instance, appears to be additive. The more genes you get for tallness, the taller you are. Unfortunately, nobody has figured out a mathematical formula for polygenetic inheritance as they have done (Hardy-Weinberg) for two alleles.
