Time Tree Versus Genealogy Question Of course, as a genealogist, my first answer would be that we always need to be cautious about user-provided trees. Even when the genealogy is accurate, that’s no guarantee there wasn’t a biological disruption that caused the genetic line not to be the...
通过clean tree v2(https://www.erasmusmc.nl/genetic_identification/resources)软件(Y单倍群树的版本为:Y-DNA Haplogroup Tree 2019-2020 version 14.07)对样本的Y单倍群进行预测。单倍群命名根据国际遗传系谱学会(International Society of Genetic Genealogy, ISOGG)的Y-DNA单倍群树(https://isogg.org/tree/index.ht...

随着测序技术的发展,越来越多的SNP位点得以被发现,其中包括部分可用于构建进化树的SNP位点,这在极大程度上扩充了Y染色体进化树,使得单倍群的划分可以愈发精细,截至2016年3月27日,国际遗传系谱学会(International Society of Genetic Genealogy,ISOGG)在线提供的可用于构建Y染色体进化树的SNP位点已达31617个。但由于这其中...
其中, 法医SNP系谱推断, 国外也称法医遗传系谱学(forensic genetic genealogy, FGG)、侦查系谱学(investigative genetic genealogy, IGG), 是通过遗传谱系分析解决涉及司法实践中身份识别的问题[3]。通过DNA与涉案人员的家族成员关联起来, 绘制家族系谱树, 进而找到涉案人员。公安部物证鉴定中心所属我项目组研发的法医SNP...
