Associations of PON1 and genetic ancestry with obesity in early childhood. [PDF]

, 2013
Obesity in children has become an epidemic in the U.S. and is particularly prominent in minority populations such as Mexican-Americans. In addition to physical activity and diet, genetics also plays a role in obesity etiology. A few studies in adults and

The Genetic Structure and History of Africans and African Americans. [PDF]

, 2009
Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic. We studied 121 African populations, four African American populations, and 60 non-African

Visualizing Genetic Programming Ancestries [PDF]

Proceedings of the 2016 on Genetic and Evolutionary Computation Conference Companion, 2016
Previous work has demonstrated the utility of graph databases as a tool for collecting, analyzing, and visualizing ancestry in evolutionary computation runs. That work focused on sections of individual runs, whereas this paper illustrates the application of these ideas on the entirety of large runs (up to three hundred thousand individuals) and ...

Meta-analysis of genome-wide association studies of asthma in ethnically diverse North American populations. [PDF]

, 2011
Asthma is a common disease with a complex risk architecture including both genetic and environmental factors. We performed a meta-analysis of North American genome-wide association studies of asthma in 5,416 individuals with asthma (cases) including ...

Ancestry inference using principal component analysis and spatial analysis: a distance-based analysis to account for population substructure

BMC Genomics, 2017
Background Accurate inference of genetic ancestry is of fundamental interest to many biomedical, forensic, and anthropological research areas. Genetic ancestry memberships may relate to genetic disease risks.

Genetic ancestries in northwest Cambodia

Annals of Human Biology, 2006
A survey of the genetic ancestry of 125 Cambodian children resident in Siem Reap province was undertaken, based on eight Y-chromosome binary polymorphisms and sequencing of the mtDNA HV1 region. The data indicated a largely East Asian paternal ancestry and a local Southeast Asian maternal ancestry.

Information on ancestry from genetic markers [PDF]

Genetic Epidemiology, 2004
AbstractIt is possible to estimate the proportionate contributions of ancestral populations to admixed individuals or populations using genetic markers, but different loci and alleles vary considerably in the amount of information that they provide. Conventionally, the allele frequency difference between parental populations (δ) has been used as the ...
