Worldwide diversity of the Y-chromosome tetra-local microsatellite DYS464.
Of all DNA markers on the human Y-chromosome, the tetra-local Y-linked microsatellite DYS464 is the most polymorphic. We genotyped DYS464 in 677 male samples collected worldwide, maintained in the HGDP-CEPH Human Genome Diversity Cell Line Panel. Fourteen different alleles were found, with allele lengths varying from 9 to 23 repeats. One hundred and seventy-five different genotypes were detecte...
متن کاملY chromosome microsatellite isolation from BAC clones
We constructed a microsatellite library from four Crocidura russula Y chromosome-specific bacterial artificial chromosome (BAC) clones. Only one of eight microsatellites was male-specific, despite genome walking to obtain more flanking sequence and testing of 93 primer combinations. Potential reasons for this low success are discussed. The malespecific locus, CRY3, was genotyped in 90 males, in...
متن کاملY-chromosome-specific microsatellite variation in a population sample from Sardinia (Italy).
The genetic variability at seven Y-chromosomal microsatellite loci was studied among 113 Sardinian males from the regions of Campidano of Cagliari, Nuorese and Gallura. The allelic and haplotypes frequency distributions are compared between our sample and from the available literature data on Mediterranean and European populations. As a result, the Sardinian samples showed a very high allele fr...
متن کاملY-chromosome polymorphisms and ethnic group – a combined STR and SNP approach in a population sample from northern Italy
AIM To find an association between Y chromosome polymorphisms and some ethnic groups. METHODS Short tandem repeats (STR) and single-nucleotide polymorphisms (SNP) on the Y chromosome were typed in 311 unrelated men from four different ethnic groups - Italians from northern Italy, Albanians, Africans from the Maghreb region, and Indo-Pakistanis, using the AmpFlSTR® Yfiler PCR Amplification Kit...
متن کاملA view of modern human origins from Y chromosome microsatellite variation.
The idea that all modern humans share a recent (within the last 150, 000 years) African origin has been proposed and supported on the basis of three observations. Most genetic loci examined to date have (1) shown greater diversity in African populations than in others, (2) placed the first branch between African and all non-African populations in phylogenetic trees, and (3) indicated recent dat...
