www.sciencemag.org SCIENCE VOL 325 3 JULY 2009 5 COVER The Phoenix spacecraft on the martian polar plains (68°N latitude). The footpad at the bottom is about 1 meter below the spacecraft deck seen at the lower left. Overlaid images are trenches dug to either nearly pure water ice or ice-cemented soil. Analyses of samples taken from these trenches give clues to the history of the region. Results from the Phoenix mission are discussed in four Reports beginning on page 58.

The American Society of Human Genetics Ancestry Testing Statement
Ancestry testing and ancestry estimation are utilized in a variety of settings. Ancestry testing is done on an individual basis, in an attempt to determine the ancestral origins or population(s) of origin for a person or family. Ancestry estimation is performed to infer biogeographical origins or admixtures of populations for research purposes. This document from the human genetics community fo...
متن کاملCOMMENTARY Inferring Genetic Ancestry: Opportunities, Challenges, and Implications
Increasing public interest in direct-to-consumer (DTC) genetic ancestry testing has been accompanied by growing concern about issues ranging from the personal and societal implications of the testing to the scientific validity of ancestry inference. The very concept of ‘‘ancestry’’ is subject to misunderstanding in both the general and scientific communities. What do we mean by ancestry? How ex...
متن کاملGenetic composition of a Brazilian population: the footprint of the Gold Cycle.
Ancestry-informative markers (AIMs) are powerful tools for inferring the genetic composition of admixed populations. In this study, we determined the genetic ancestry of the Ouro Preto (Brazil) population and evaluated the association between ancestry and self-reported skin color. The genetic ancestry of 189 children and adolescents was estimated by genotyping 15 AIMs. The estimate of populatio...
متن کاملInformativeness of genetic markers for inference of ancestry.
Inference of individual ancestry is useful in various applications, such as admixture mapping and structured-association mapping. Using information-theoretic principles, we introduce a general measure, the informativeness for assignment (I(n)), applicable to any number of potential source populations, for determining the amount of information that multiallelic markers provide about individual a...
متن کاملSummary: the science of genealogy by genetics.
This summary lays out the basic science and methodology used in genetic testing that investigates historical population migrations and the ancestry of living individuals. The genetic markers used in this testing, and the distinction between Y-chromosome, mitochondrial and autosomes analysis, are explained and the shortcomings of these methodologies are explored.
