I dont get it. In biology they told us that theres recessive and dominant genes. And when a child has lets say a black father and a white mother, the doninant black gene will be stronger. Meaning he should be black but with a recessive white gene as well. But theyre mostly lighter black meaning the supposedly "recessive gene had an impact in skin colour". So far you can say "ok that makes kinda sense".
If that black child with recessive white genes THEN grows up to meet a white person, the children have a 50% chance to turn out white. But in the other 50% the child doesnt lighten up much, it kinda just stays that colour. How the fuck does that work? The white recessive gene although being recessive bleaches in the first gen but doesnt in the second??
