Resumen
Descripción general del contenido del recurso.
The aim of this article is to estimate the genetic composition of the population of Comodoro Rivadavia (CR) and to compare the data with those obtained previously in the Area Metropolitana de Buenos Aires (AMBA) and Bahía Blanca (BB). The study was performed on 72 unrelated donors. Five erythrocyte genetic markers, Gm allotypes, mtDNA and Y chromosome DYS199 locus were analysed. An inquiry was performed to obtain information about the place of birth, present residence and genealogical data. The gene frequencies were calculated using a method of maximum likelihood and for mitochondrial haplogroups and DYS199 locus direct count was used. The gene admixture was estimated through the ADMIX programme. The protein genetic markers showed 37% and 4% of indigenous and African components, respectively. Seventy percent of the mitochondrial lineages were of Amerindian origin, however, we did not fi nd any of subsaharian origin. Six percent of the males analysed had the aboriginal variant DYS199*T. These differences in the sex-specific contribution seem to reveal an asymmetric contribution by gender in the history of this population. Both the uniparental and biparental markers showed higher values of Amerindian contribution in CR with respect to those of AMBA and BB, but values of the African component were similar.
