“…For this purpose, the trihybrid model of admixture for the Monterrey population was fitted with contributions from three parental populations: Spanish, Amerindian, and African. As representative of ancestral populations, gene frequency data from the Southwestern region of Spain were obtained from Gamero et al (2000). Pooled allele frequencies from several Southwestern Amerindian communities (Apache, Navajo, and Pueblo) represented the Amerindian ancestral allele frequencies (unpublished data from U.S. Scientific Working Group of DNA Analysis Methods, [SWGDAM]; see also Budowle et al, 2001).…”

Tetrameric short tandem repeat (STR) polymorphisms are widely used in population genetics, molecular evolution, gene mapping and linkage analysis, paternity tests, forensic analysis, and medical applications. This article provides allelic distributions of the STR loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, CSF1PO, TPOX, TH01, and D16S539 in 143 Mestizos from Northeastern Mexico, estimates of contributions of genes of European (Spanish), American Indian and African origin in the gene pool of this admixed Mestizo population (using 10 of these loci); and a comparison of the genetic admixture of this population with the previously reported two polymorphic molecular markers, D1S80 and HLA-DQA1 (n = 103). Genotype distributions were in agreement with Hardy-Weinberg expectations (HWE) for almost all 13 STR markers. Maximum likelihood estimates of admixture components yield a trihybrid model with Spanish, Amerindian, and African ancestry with the admixture proportions: 54.99% 3.44, 39.99% 2.57, and 5.02% 2.82, respectively. These estimates were not significantly different from those obtained using D1S80 and HLA-DQA1 loci (59.99% 5.94, 36.99% 5.04, and 3.02% 2.76). In conclusion, Mestizos of Northeastern Mexico showed a similar ancestral contribution independent of the markers used for evolutionary purposes. Further validation of this database supports the use of the 13 STR loci along with D1S80 and HLA-DQA1 as a battery of efficient DNA forensic markers in Northeastern Mestizo populations of Mexico.

Five loci (vWA1, F13A1, D12S67, Apo-B and D1S80) were investigated by polyacrylamide gel electrophoresis followed by silver staining in a sample of 177 individuals from the population of São Luís, State of Maranhão, Brazil. A total of 70 different alleles were identified. A statistically significant deviation from the Hardy-Weinberg equilibrium was observed in a single locus (F13A1, p = 0.0075). The average heterozygosity (H) was estimated at 77.7%, the mean number of alleles per locus as 14. The PD (capacity of genotype differentiation at each locus) ranged from 88.9% (vWA1) to 96.7% (F13A1). The combined PE (power of exclusion) of these five loci was 99.8%. In terms of racial admixture (42% European, 39% Indian, and 19% African Black ancestry), São Luís presented an estimate similar to Belém, another trihybrid Amazonian population.

“…The origin of the Chocó population is from slaves brought from Africa in the middle of the seventeenth century, mainly from Mauritania, Mozambique, the Guinea Gulf area, Sao Tomé, South Congo and Angola (Cuesta 1986). STR population data from these areas can be found in Gamero et al (2000), Gusmao et al (2001) and Corte-Real et al (1999). The aim of this paper is to contribute to the establishment of a Colombian database for the polymorphisms of forensic interest.…”

Genetic data for eight autosomal STRs were obtained from two different population samples from Colombia: the European Mestizo population of Bogotá and the African descent population of the Chocó region. The STRs were analysed in a multiplex system that includes the STR markers CSF1PO, TPOX, TH01, VWA, D13S317, D7S820, D16S539 and D5S818. Separation of the fragments and fluorescent detection was carried out in an ABI 310 DNA sequencer and the typing was made by comparison with sequenced allelic ladders. Exact tests were used for testing linkage between the loci and for Hardy-Weinberg equilibrium. Significant differences were found between both populations for all the loci.
