Diversidad genética de materiales nativos de aguacate guatemalteco a través del marcador molecular AFLP

Cienc. tecnol. salud; 7 (2), 2020
El aguacate es un cultivo de consumo a nivel mundial, y según teorías recientes, se sugiere a la región de la Sierra Nevada, en California, como centro de origen y, a Guatemala, como uno de los principales centros de domesticación. Mediante caracterizaciones morfológicas se ha reportado una alta div...

Selective intra-dinucleotide interactions and periodicities of bases separated by K sites: a new vision and tool for phylogeny analyses

Biol. Res; 50 (), 2017
Direct tests of the random or non-random distribution of nucleotides on genomes have been devised to test the hypothesis of neutral, nearly-neutral or selective evolution. These tests are based on the direct base distribution and are independent of the functional (coding or non-coding) or structural (rep...

Dermatoglyphic traits of six Chibcha-speaking Amerindians of Costa Rica, and an assessment of the genetic affinities among populations

Rev. biol. trop; 57 (supl.1), 2009
Dermatoglyphic traits have been used to evaluate population structure and microdifferentiation in several populations. For Chibcha-speaking groups of Lower Central America there are few dermatoglyphic studies, but extensive linguistic, anthropological and genetic data support their historical, cultural a...
