Genetic variation at twentythree microsatellite loci in sixteen human populations
(1999-08)
We have analysed genetic variation at 23 microsatellite loci in a global sample of 16 ethnically and geographically diverse human populations. On the basis of their ancestral heritage and geographic locations, the studied ...
Climatic stability and contemporary human impacts affect the genetic diversity and conservation status of a tropical palm in the Atlantic Forest of Brazil
(2017-04-01)
Understanding how historical and current environmental suitability and human impacts affect the genetic diversity on a large scale is essential to species management planning. However, most studies in conservation genetics ...
Exclusion of known gene for enamel development in two Brazilian families with amelogenesis imperfecta
(2007-07-02)
Amelogenesis imperfecta (AI) is a genetically heterogeneous group of diseases that result in defective development of tooth enamel. Mutations in several enamel proteins and proteinases have been associated with AI. The ...
Global genetic variation at nine short tandem repeat loci and implications on forensic genetics
(European Journal of Human Genetics (2003) 11, 39 – 49, 2003-01)
We have studied genetic variation at nine autosomal short tandem repeat loci in 20 globally distributed
human populations defined by geographic and ethnic origins, viz., African, Caucasian, Asian, Native
American and ...
Atlantic forest fragmentation and genetic diversity of an isolated population of the Blue-manakin, Chiroxiphia caudata (Pipridae), assessed by microsatellite analyses
(2006-03-01)
Habitat fragmentation is predicted to restrict gene flow, which can result in the loss of genetic variation and inbreeding depression. The Brazilian Atlantic forest has experienced extensive loss of habitats since European ...
Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals
(Public Library of Science, 2014)
The current genetic makeup of Latin America has been shaped by a history of extensive admixture between Africans, Europeans and Native Americans, a process taking place within the context of extensive geographic and social ...
