huh. So where does the dominant/recessive traits we learn about in high school play into that?
I ask because my niece had blue eyes as a baby. This didn't make any sense because my sister was Indian, our parents were from India, their parents were from .. well I guess now it's Pakistan, but they migrated during the partition.
My sister married a white dude, but still it seemed very unlikely her daughter wouldn't have brown eyes. That's when we found out my grandmother got her education in Europe, and came back pregnant. Apparently divorces at the time were so shameful that it was better to tell your child their parent died.
My nieces eyes are now a bit hazel/blue-green ish. My grandmother passed away not too long after that, and that secret would have died with her, if it wasn't for the fact that my niece had blue eyes.
Not sure where your question comes from - one common ancestor could nonetheless have had a recessive trait (though selection for it might not kick in until it was visible.) It's not directly relevant, but I might mention there are many sorts of genetic combos/phenotype patterns, not just plain recessive and dominant.
