The Y chromosomes of 549 individuals from Siberia and the Americas were analyzed for 12
biallelic markers, which defined 15 haplogroups. The addition of four microsatellite markers …

In a study of 908 males from Europe, northern Africa, and western Asia, the variation of four
Y-linked dinucleotide microsatellites was analyzed within three" frames" that are defined by …

A polymorphic C--> T transition located on the human Y chromosome was found by the
systematic comparative sequencing of Y-specific sequence-tagged sites by denaturing high …

We examined DNA polymorphisms in the nonrecombining portion of the Y-chromosome to
investigate the contribution of distinct patrilineages to the present-day white Brazilian …

It has been proposed that women had a higher migration rate than men throughout human
evolutionary history. However, in a recent study of South American natives using mtDNA …

In this study, 231 Y chromosomes from 12 populations were typed for four diagnostic single
nucleotide polymorphisms (SNPs) to determine haplogroup membership and 43 Y …

To evaluate sex-specific differences in gene flow between Native American populations from
South America and between those populations and recent immigrants to the New World, we …

We examined variation on the nonrecombining portion of the human Y chromosome to
investigate human evolution during the last 200,000 years. The Y-specific polymorphic sites …

We surveyed nine diallelic polymorphic sites on the Y chromosomes of 1,544 individuals
from Africa, Asia, Europe, Oceania, and the New World. Phylogenetic analyses of these nine …

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 …
