I don't know what you mean by your sentence below. Genes are only
transmitted from generation to generation as pieces of a chromosome which
were "crossed over" and recombined to form whole chromosomes again, and then
randomly selected from two choice of that chromosome to be placed in the
offspring. If detrimental genes reduce chances of human to reproduce, the
whole pieces of chromosome which were crossed over and containing the
detrimental gene suffer in the subsequent population. And vice-versa for
the positive genes. I reread your sentence again and again, and I can't
fathom what you are saying.

Actually, I'm not sure genes are the right unit to
