Distribution of Y-chromosomal SNP G - and A-oY 1 in modern sheep breeds in Europe, Asia and Africa and in ancient Finnish sheep. Ancient sheep are indicated by a smaller circle over Finland at the northern most location on the map; the remaining circles on the map indicate modern sheep breeds from [9, 12] listed in [Additional file 4: Table S3]; the proportions of G-oY 1 and A-oY 1 haplotypes are indicated in red and green, respectively; the size of the circles is proportional to sample size in each location.
