By May 2023 about 350,000 Y chromosomes typed for 9-29 STR loci have been directly submitted by worldwide forensic institutions and universities. In geographic terms, about 53% of the YHRD samples stem from Asia, 21% from Europe, 12% from North America, 10% from Latin America, 3% from Africa, 0.8% from Oceania/Australia and 0.2% from the Arctic.
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 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 chromosome was a particularly hard nut to crack because it is unusually repetitive. The four letters or building blocks of DNA — adenine (A), cytosine (C), guanine (G) and thymine (T ...
The Kerey clan of the Kazakhs have a high amount of the C3* star-cluster (C2*-ST) Y chromosome and is very high among Hazaras, Kazakhs and Mongols in general. [85] Toghan, Genghis Khan's sixth son has claimed descendants who have Y haplogroup C2b1a1b1-F1756 just like the first son of Genghis Khan, Jochi's descendants in the Kazakh Tore clan. [83]
Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that ...
