  1. The frequencies of the major haplogroups were calculated and values are represented as a percentage of the total number of individuals in that region. The “Other” column represents haplogroups (F, G, N, Q and T) that were only seen once or twice in the regions (primarily the English population). The R1b-M222 haplogroup, a subclade included as part of the R1b-M343 haplogroup, is also shown separately as it represents 23.9% of the total Irish Y chromosomes.
