Latest Human genetic variation Stories
Combining family- and population-based approaches sheds new light on the potential roles of both common and rare forms of human genetic variation.
In a study published in the September 24th issue of Nature, an international team describes how they harnessed modern genomic technology to explore the ancient history of India, the world's second most populous nation.
A newly designed computational method has proven its usefulness in counting copies of duplicated genome sequences and in doing initial assessments of their contents, according to a study to be published Aug. 30 in Nature Genetics. The number of copies of particular DNA segments can differ from one person to the next.
In a pioneering effort that generated massive amounts of DNA sequence data from 12 people, a team supported by the National Institutes of Health (NIH) has demonstrated the feasibility and value of a new strategy for identifying relatively rare genetic variants that may cause or contribute to disease. The proof-of-concept findings were published online today in the journal Nature.
At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from.
Through sophisticated statistical analyses and advanced computer simulations, researchers are learning more about the genomic patterns of human population structure around the world.
Cornell University scientists have created a computer program that examines small differences in people's genes to identify big events in human history. The researchers said their program can pinpoint the origins of specific gene mutations, shedding light on times when the human population moved close to extinction and helping scientists study gene mutations that make some demographic groups more likely to develop diseases such as cancer, heart disease and diabetes. We know that many diseases...
A 10-year study of African population genetics has determined the continent is the most genetically diverse in the world, researchers said Thursday. The team headed by Sara Tishkoff, a geneticist at the University of Pennsylvania, determined that modern humans evolved in southern Africa on the border between Namibia and South Africa.
An international team of researchers has reported the largest-ever study of genetics in Africa that helps pinpoint where human evolution began.
For two decades, researchers have been using a growing volume of genetic data to debate whether ancestors of Native Americans emigrated to the New World in one wave or successive waves, or from one ancestral Asian population or a number of different populations.
