More than 2700 unrelated individuals from Europe, northern Africa and western Asia were analyzed for the marker M269, which defines the Y chromosome haplogroup R1b1b2. A total of 593 subjects belonging to this haplogroup were identified and further analyzed for two SNPs, U106 and U152, which define haplogroups R1b1b2g and R1b1b2h, respectively. These haplogroups showed quite different frequency distribution patterns within Europe, with frequency peaks in northern Europe (R1b1b2g) and northern Italy/France (R1b1b2h).
对来自欧洲、北非和西亚的 2700 多个无关个体进行了标记 M269 的分析，该标记定义了 Y 染色体单倍群 R1b1b2。共鉴定出属于该单倍群的 593 个个体，并进一步分析了定义单倍群 R1b1b2g 和 R1b1b2h 的两个 SNP，U106 和 U152。这些单倍群在欧洲内部呈现出截然不同的频率分布模式，在北欧（R1b1b2g）和意大利/法国北部（R1b1b2h）呈现出频率高峰。
