๐ฎ๐ช Genetic Landscape of Ireland
Ireland holds one of the world's most distinctive genetic profiles. The Irish have the highest rate of red hair on Earth (~10%), the highest frequency of O blood type in Europe (~55%), and an unusually high rate of Celtic genetic markers (R1b haplogroup) found in ~80% of Irish men. Ireland's island geography created a genetic bottleneck that preserved these rare traits. The phrase 'Black Irish' refers to dark-haired Irish people, whose features may trace to Spanish Armada survivors or pre-Celtic inhabitants.
