A gene being dominant over another (recessive) one doesn't mean it has more chances of getting passed on. If you have a dominant allele from one parent and a recessive one for the same trait from the other, the chances of your child having one is 50%, and so are those of it having the other. This means that two "halfwhites" can still make a fully white baby together.
Human DNA doesn't come in percentages or fractions. It comes in chromosomes (23 from either parent) and in mitochondrial DNA (which you get from your mother).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
