In this image, each vertical bar represents an individual, and
each element of European ancestry is represented by a color:
Basque (purple), Spanish (yellow), southern European (red),
continental European (green), and northern European (pink). The
mix of colors within an individual bar represents the proportion
of each of five possible ancestries in the analysis. The Greeks,
for example, mostly have markers linked to southern Europeans,
with a few markers affiliated with Northern Europeans and
continental Europeans. The neighboring Italians have a more
varied profile, with some individuals having significant numbers
of markers linked to the Basque and northern European
populations. The Germans and east English also have a varied
profile, possessing markers linked to all five groups. In a
study published last year, Mark Shriver and his team at
Pennsylvania State University analyzed 10,000 genetic markers in
nearly 300 people of Armenian, Jewish, Greek, Spanish, Basque,
French, Italian, German, English, Irish,
