The geographic structure of Y-chromosome variability has been analyzed in native
populations of South America, through use of the high-frequency Native American …

We analysed the frequency of six Y‐specific polymorphisms in 105 Amerindian males from
seven different populations, 42 Caucasian males, and a small number of males of African …

We defined the Y-chromosome haplotypes on the basis of six polymorphic sites: an Alu-
element insertion (YAP), a single-base change (C→ T at DYS199), one trinucleotide repeat …

To scrutinize the male ancestry of extant Native American populations, we examined eight
biallelic and six microsatellite polymorphisms from the nonrecombining portion of the Y …

Recently we reported the discovery of a major Y chromosome founder haplotype in
Amerindians from South and Central America (Pena et al. 1995). We haplotyped Y …

Sixteen Y-chromosomal microsatellites and 16 binary markers have been used to analyze
DNA variation in 408 male subjects from 15 populations in Central Asia. Large genetic …

To investigate geographic structure within US ethnic populations, we analyzed 1705
haplotypes on the basis of 9 short tandem repeat (STR) loci on the Y-chromosome from 9 …

Recently, Y chromosome markers have begun to be used to study Native American origins.
Available data have been interpreted as indicating that the colonizers of the New World …

The human Y chromosome contains highly informative markers for making historical
inferences about the pre‐Columbian peopling of Americas. However, the scarcity of these …

We analyze the allelic polymorphisms in seven Y-specific microsatellite loci and a Y-specific
alphoid system with 27 variants (αh I–XXVII), in a total of 89 Y chromosomes carrying the …
