I think that few people appreciate the scale of the 1,000 Genomes Project and just how much information it's already yielding about human genetic variation.

Not exact matches

in the May issue claims that biologists say the concept of race is biologically meaningless, presumably because «any large human population has about 85 percent as much genetic variation as the species as a whole.»

Variation in pigmentation among human populations may reflect local adaptation to regional light environments, because dark skin is more photoprotective, whereas pale skin aids the production of vitamin D. Although genes associated with skin pigmentation have been identified in European populations, little is known about the genetic basis of skin pigmentation in Africans.

An international consortium of researchers in the Genotype - Tissue Expression (GTEx) Consortium published findings about how genetic variation effects gene regulation in 44 human tissue types.

But new genetic studies of ancient DNA from Neandertals have found that they and the last ancestor they shared with humans, about 600,000 years ago, also lacked much genetic variation, which would require at least three dramatic bottlenecks — an improbable scenario.

I was working in a community of people who were all thinking about looking at genetic variations, of how you might look at them and how you might understand them, and so reading lots of papers from other folks who were doing great work in that area I just looked at ways that you could basically go across the human genome and look at every variation, everything that's variable between human populations.

«Genetic recombination is a fundamental process, at the core of reproduction and evolution,» said study author Graham Coop, PhD, post-doctoral fellow in the Department of Human Genetics at the University of Chicago, «yet we know very little about where it occurs or why there is so much variation among individuals in this important process.»

We can explain about 20 % of the variation in human body size with about 700 genetic variants1.

Increased understanding about how environmental variations, such as socio - economic disparities, affect human brain development and behavior has significant implications for advancing basic scientific questions such as understanding genetic versus environmental contributions of brain and behavioral development.
