What would the average skin tone and facial features look like after 300 years if every partner relationship was interracial until there were no other ethnicities? Just a hodgepodge of DNA. What would the average human look like having a little bit of everything in them?
I just think the idea is neat is all.
Measured at what age? You definitely don’t have the same skin now as newborn you. Skincolor is dependend as much on nutritional and eviromental factors as it is on genetic ones. In addition to that the genes don’t simply average out your skin tones. There are enough examples of “interracial” couples having 2 children, one being dark skinned and the other being pale. Your base melanin levels and additional melanin production are two entirely different and independend genetic factors.
Fair enough, measured at 25 and with a healthy nutrition and they do see the sun regularly. That answers the skin tone, but what about facial features? When it is all said and done, what features might take over? Like eye, nose, and mouth shape.
