I asked a question about recessive genes. The answers that I got
totally disabused me of the understanding I previously had about this
subject.

I actually thought that "recessive" genes were the genes that "lost
out" in some kind of cellular competition between chromosomes.

For instance recently, from the television, I heard that "blue
eyes" are the product of "recessive genes". To be honest, in the
context of what I've been told here, I don't really understand
that.

I had thought that, in a given individual with the genetic
determination to have "blue eyes", that they would have "blue
eyes" unless they also had some (less recessive) genetic admixture
which would overrule that result and produce another.

Okay, I have a new question: When a Black person and a White person
have a child, why is it that (in my opinion) the characteristics of the
child appear as an "averaging" of the parents traits? For instance,
their skin color, body shape and so on.

What I want to know is: how is it possible for the two sets of genes to
work together and yet interfere with each others results? And to do so
in a way that seems predictable and regulated.
