So true. May mother was one of 6 children. They were equally divided between the dark ones and the blond ones. The dark ones were clearly showing the Asiatic input from the Mongol incursions into eastern Europe. Her mother was from East Prussian petit nobility, and her father from Poznan(Posen) Poland. My husband was a clear blue eyed redhead with Scottish ancestry. I have hazel eyes. One son was dark haired, and the other lighter brown haired. They both have very dark brown eyes. I figure they got my weaker dark brown Asian eye gene which was suppressed by my European eye genetics, but was stronger than the pure light blue gene from my husband. I also think my husband had more than the 4% Neanderthal genes some of us are supposed to have.
We had a guy in the Marines back in the 70’s who was so hairy he looked like he had on a fur coat...................
