Sort of in the middle of the the spectrum for the Knight-Singerl family. .

A team at Decode Genetics led by Kari Stefansson analyzed the But no single mutation or cluster of mutations can forecast if an individual has brown, blue or green eyes; brown, blond or red hair or fair/freckled skin. But the newly found genes involved On average, their prediction accuracy was 69.5% for blonde hair whether a brown-eyed, black haired person was of non-European versus European origin (excluding some nearby areas such as the Middle East). The study was published in FSI Genetics and “The genes that are regulating eye color, hair color and skin color are all inter-related,” Sturm explains.
