Y-chromosomal haplogroup H1a1a-M82 founder analysis for Roma.

Different founders were identified based on the Network analysis (Text S1). The age was estimated from the ρ statistic (the mean number of mutations from the assumed root of each and every founder), using a 25-year generation time and the TD statistic, assuming a mutation rate of 6.9×10−4[11], based on variation at 15 common Y-STR loci.

本研究通过网络分析（Text S1）鉴定出多个奠基者个体。奠基者的年龄通过ρ统计量进行估算，该统计量指每个奠基者对应的假设系统发育根的平均突变数；本次年龄估算采用25年的世代时间与TD统计量，基于15个常见Y染色体短串联重复序列（Y-chromosome Short Tandem Repeat, Y-STR）位点的遗传变异，并设定突变率为6.9×10⁻⁴[11]。
