Logo of the Y Chromosome Haplotype Reference Database (YHRD) version 4.0. The Y Chromosome Haplotype Reference Database (YHRD) is an open-access, annotated collection of population samples typed for Y chromosomal sequence variants. [1]
Y-chromosome Database: The Y chromosome is passed on from father to son with little changes to Y-DNA. Surnames also tend to generally be passed on from father to son. The Sorenson Database used Y-chromosome genetic markers and surnames to determine common ancestors. Users could share DNA results and pedigree charts obtained from other sources ...
The Y chromosome is one of two sex chromosomes in therian mammals and other organisms.Along with the X chromosome, it is part of the XY sex-determination system, in which the Y is the sex-determining chromosome because the presence of the Y chromosome causes offspring produced in sexual reproduction to be of male sex.
In accompanying research published in the same journal on Wednesday, a collaborating team of scientists assembled Y chromosomes from 43 male individuals from 21 world populations to capture ...
Researchers on Wednesday unveiled the first complete sequence of the human Y chromosome, which is one of the two sex chromosomes - the X chromosome being the other - and is typically passed down ...

In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
The Y-STR markers in the following list are commonly used in forensic [1] and genealogical DNA testing. DYS454 is the least diverse, and multi-copy marker DYS464 is the most diverse Y-STR marker. The location on the Y-chromosome of numbered Y-STR markers can be roughly given with cytogenetic localization. For example, DYS449 is located at Yp11 ...
