Genographic Project study gives insight into origins of Afghan population A study by The Genographic Project has found that the majority of all known ethnic Afghans share a unique genetic heritage derived from a common ancestral population that most likely emerged during the Neolithic revolution and the formation of early farming communities. Through detailed DNA analysis of samples from 27 provinces, the Genographic team found the inter-Afghan genetic variability to be mostly attributed...

Large numbers of people moved between Africa and Europe during recent and well-documented time periods such as the Roman Empire, the Arab conquest, and the slave trade, and genetic evidence of these migrations lives on in Europeans today. But were there more ancient migrations? In a study published online today in Genome Research, researchers present the first genetic evidence for prehistoric gene flow between Africa and Europe, dating back as far as 11,000 years ago. To trace the...

A recent large and comprehensive analysis of 50,000 genetic variants across 2,000 genes linked to cardiovascular and metabolic function has identified four genes associated with type 2 diabetes (T2D) and six independent disease-associated variants at previously known loci. The findings, which provide valuable insight into the genetic risk for T2D across multiple ethnicities, add to the growing list of genetic variants that affect the risk of developing T2D and could pave the way for...

The timing and pattern of the migration of early modern humans has been a source of much debate and research. Now, a new study uses genetic analysis to look for clues about the migration of the first modern humans who moved out of Africa more than 60,000 years ago. The research, published January 26 by Cell Press in the American Journal of Human Genetics, the official journal of the American Society of Human Genetics, provides intriguing insight into the earliest stages of human migration and...

A tiny mountainous region in southern Siberia may have been the genetic source of the earliest Native Americans, according to new research by a University of Pennsylvania-led team of anthropologists. Lying at the intersection of what is today Russia, Mongolia, China and Kazakhstan, the region known as the Altai "is a key area because it's a place that people have been coming and going for thousands and thousands of years," said Theodore Schurr, an associate professor in Penn's Department...

While environment and family history are factors in healthy aging, genetic variants play a critical and complex role in conferring exceptional longevity, according to researchers from the Boston University Schools of Public Health and Medicine, Boston Medical Center, IRCCS Multimedica in Milan, Italy, and Yale University. Published in PLoS ONE, after peer review, the research findings are the corrected version of work originally published in Science in July 2010. The revised publication...

Smut fungi can mate with other species despite great genetic differences Two-timing is nothing out of the ordinary for them: for about 100 million years, grass smut fungi have been breeding in a three-gender system. This was discovered by Dr. Ronny Kellner and Prof. Dr. Dominik Begerow of the RUB Geobotany Laboratory in cooperation with colleagues from the Heinrich Heine Universität in Düsseldorf. Using genetic analysis, they showed that the structure of the...

The cocktail maintaining immune gene variation The great variation of a specific form of immune genes makes organ transplants so complicated. On the other hand, we need such a great variability in order to resist infectious diseases. This is why it also plays a major role in the selection of sexual partners. Up until now, the mechanisms for maintaining this standing genetic variation have remained an evolutionary puzzle. In a study of sticklebacks, researchers from the Max Planck Institute...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
