HaplogroupJ1(Y-DNA)在人类遗传学,和脱氧核糖核酸单倍群J,也被称为j-m267,是一个sub-haplogroup的脱氧核糖核酸单倍群,连同其亲缘分支的脱氧核糖核酸单倍群..
HaplogroupR1a(Y-DNA) 单倍群r1a是进化的主要分支的人类Y染色体脱氧核糖核酸单倍群。换句话说, 它是一种方式分组的一个重要部分的所有现代人根据共同的祖先,男线。这是在 许多地区的欧亚大陆,经常讨论在人类群体遗传学和遗传系谱。一个sub-clade (分公司)的r1a,目前指定的r1a1a,是较为普遍比其他所有主要地理区域...
In 2006, the first year that ISOGG compiled a SNP tree,the number of Y DNA haplogroups was 460, including singletons, not tens of thousands. No one would ever have believed this SNP tsunami would happen, let alone in such a short time. Naming SNPs Family Tree DNAwaiting to name SNPs ...
This is especially relevant for project administrators who are familiar with family groups and know that people who are in the same surname group should share a common base haplogroup, although some people who have taken further SNP testing will be shown with a downstream haplogroup, further down ...
From Family Tree DNA: Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype...
Before starting NRY haplogroup classification, we firstly divide markers of each haplogroup on the ISOGG Y-DNA tree into two classes: key and ordinary. The key markers are those traditionally used or tested in labs, which are displayed in bold on the ISOGG Y-DNA tree. To classify haplogroup ...
To define the genomic position of the functional centromere on the Y chromosome, we examined the enrichment profiles of inner kinetochore centromere protein A (CENP-A), a histone H3 variant that replaces histone H3 in centromeric nucleosomes, using a Y-haplogroup-matched cell line that offers a...
2 Maximum-parsimony tree of 44 Y chromosome haplogroups together with their frequencies in Japan and five Asian regions. Samples sizes for each region: Japan 259; northeast Asia (NEA) 441; Southeast Asia (SEA) 683; central Asia (CAS) 419; south Asia (SAS) 496; Oceania (OCE) 209. Major...

34] and was found to be located on the short arm of the Y chromosome close to the pseudoautosomal boundary. This gene is thought to have been evolved by a mutation in theSOX3gene. The humanSRYis a single exon that encodes a protein of 204 amino acids which contains a conserved DNA-...
