Universidad de Barcelona; Barcelona: Polimorfismos de 17 marcadores STR del cromosoma-Y en una muestra poblacional del altiplano cundiboyacense.

Generally, a sample size between individuals is considered an adequate sample size for forensic frequency estimations.

Sebastian Reinosa marked it as to-read Oct 07, Analisis del Mestizaje Spanish Edition. Pre- and post-Columbian patterns of gene flow in South America. Withoutabox Submit to Film Festivals. This rare … More. As has been found for other Amerindian tribes, these three parameters have evolved together in a historical and strongly correlated fashion. The haplogroup frequency of each population was estimated by direct counting Table 1Figure 1.

Most mtDNA polymorphisms are single nucleotide substitutions, emlio insertions and deletions have also been described Brown et al.

Yunis–Varon syndrome – Wikipedia

Origin and evolutionary relationships of native Andean populations. From the unrelated individuals, a total of haplotypes were determined. Table 3 Mantel test correlating genetic, linguistic and geographical distances for 21 Colombian Amerindian populations studied.

Our results showed a high degree of mtDNA diversity and genetic heterogeneity.


The first immigrants from Spain and Portugal founded the first non-Amerindian villages in present day Colombia in the early 16 th Century Inganos, Paeces y Coconucos: Major mitochondrial DNA haplotype heterogeneity in highland and lowland Amerindian populations from Bolivia. Matrix 1 Matrix 2 r p-value Genetic Linguistic 0. All Formats Paperback Hardcover Sort by: At least two of four mitochondrial haplogroups were present in the 21 populations studied.

This result is probably due to the fact that the Arab admixture of the Colombian population has been mainly with Lebanese and Palestinian populations and not with Arab populations of North Africa.

Proficiency testing for these STRs has been carried out for ystr. Haplotypes, Y chromosome, genetics, Colombia. Provide feedback about this page. More about this item Statistics Access and download statistics. The correlation analysis between the geographical, linguistic and genetic data Table 3 showed the highest correlation value for the linguistic-geographical pair followed by the genetic-geographic comparison. High-resolution analysis of human Y-chromosome variation shows a sharp discontinuity and limited gene flow between northwestern Africa and the Iberian Peninsula.

An exception was found for the Arsario tribe, where none of the individuals tested in this Chibcha speaking tribe carried haplogroup A. Although our studies did not include the DYS loci analyzed in that report, we evaluated the presence of the Cohen modal haplotype based on the remaining 5 STRs analyzed in our sample and in the sample reported for Medellin by Builes et al. An integrated software package for population genetics data analysis.

In the present study, we have analyzed the Y-chromosome haplotype data from unrelated individuals, of African descent and Caucasian-Mestizos of Colombia in order to determine the Y chromosome haplotype origin of the two population groups tested.

Recently, one Alu subfamily was found to be human specific HS. North East and Pacific Open in a separate window.

Several populations from Europe, Asia and the United States have been typed for the Y chromosome minimal haplotype and their haplotype frequencies have been reported to the Y chromosome reference database YHRD Other studies have not analyzed the Y chromosome minimal STR haplotype If you are a registered author of this item, you may also want to check the “citations” tab in your RePEc Author Service profile, as there may be some citations waiting for confirmation.


Ancient teeth, bone and tissue as sources of DNA. RePEc uses bibliographic data supplied by the respective publishers. The AMOVA analysis based on linguistic affiliation was used to test for differences based on belonging or not to the Chibcha linguistic family Table 2. Skip to search form Skip to main content.

Is haplogroup X present in extant South American Indians? When requesting a correction, please mention this item’s handle: In addition we calculated the degree of genetic differentiation among subpopulations G ST based on the genetic diversity of the total population. Our results with Y-STR haplotypes are in agreement with our previous findings, as well as historical data suggesting a common origin in the West coast of Africa for both the African American and Afro-Colombian individuals.

On the other side, Amerindian admixture is stronger in the southwest and decreases towards the north section of the Andes were the Caucasian component is stronger. Length mutations in human mitochondrial DNA. In recent years, the analysis of Y chromosome polymorphisms has become an important tool for anthropological studies as well as in regular forensic casework Features of YVS include growth retardation before and after birth, defective growth of the bones of the skull along with complete or partial absence of the shoulder blades and characteristic facial features.
