usually but not always; pure dark will dominant pure light; but dark with a recessive light will not be as dominant.

read an article that all of the asian peoples have selection of about 3-6% of specific genes from the same earlier evolved races. if you do natural inheritance of meiotic selection the odds would 'probably' only be about another 4-6% for a darker child.

Genetics is a biology, and in genealogy we don't research genes but dead ancestors... however if you look there is lots online like this

You would get a better answer if you posted this to a biology group. Genealogy is not biology. Human skin color is governed by several genes, which are not related to hair and eye color. It is not one gene that works by the highly simplified dominant-recessive rules taught in many introductory courses. It is nonsense that genes from the father are "more dominant" than genes from the mother. You have misunderstood something or your "professor" does know what he is talking about. In short, yes it is possible for a child to be lighter skinned (or darker skinned) than its father.

I know 2 sisters and mother is white and father black from Jamaica . Only from their curly hair I could tell that one of parents was black . Dominant really means that no matter how many generations you try to "bleach" next generations with only white parents and never again black once after i don't know how many generations one baby will be born completely black that you would think that both parents are black . I will apologize right now if somebody might find what I wrote wrong in any way as english is not my first language and I just didn't find any other way to say it .

Darkerhair and eyes tend to be dominant but it will depend wholly on the genetic background of BOTH parents. Dna is inherited equally from both parents, but autosomal (which influences colouring) can be unevenly inherited even between siblings. One of a family could inherit granny's looks, the other dad's. It is all 'chance'. In my own family my father was grey eyed with medium brown hair, my mother dark brown haired with green/brown eyes. All children have dark brown hair (one near black), two with hazel eyes (brown with green-darker than our mother's) and one with blue. My sister, hazelb eyed with very olive skin, married a man with light blondish-brown hair and blue eyes; none of their kids were as dark as her, with only one having brown eyes out of 3...but her grand daughter is very dark and resembles our family.
