Affordable Access to DNA Testing Reveals Family History, Genetic Cousins, Ancestral Occupations, Geographic Origins and More PROVO, Utah, Jan. 27 /PRNewswire/ -- Ancestry.com, the world's largest online resource for family history, has reduced the prices of its genetic genealogy DNA tests, allowing consumers more affordable access to the family history information provided by these tests. Effectively immediately, the 33-marker paternal lineage test is now only $79 (down from $149). The...

Laws banning marriage between first cousins are based on outdated assumptions about a high degree of genetic risk, New Zealand and U.S. researchers said. In an opinion article published in the journal PLoS Biology, Hamish Spencer of the University of Otago in New Zealand and Diane Paul of Harvard's Museum of Comparative Zoology, write that laws against cousin marriage are ill-advised. Neither the scientific nor social assumptions behind such legislation stand up to close scrutiny, Spencer...

REYKJAVIK, Iceland, December 15 /PRNewswire-FirstCall/ -- - Findings Point to Potential Therapeutic Pathways and Provide Widening Basis for the Development of a Risk Assessment Test Scientists from deCODE genetics (Nasdaq:DCGN) and colleagues from Australia and Denmark today report the discovery of common single-letter variations (SNPs) in the human genome linked to low bone mineral density (BMD), the clinical measurement used to diagnose osteoporosis. deCODE had previously...

Scientists encourage 'continuous and effective management' and further study of these 'spectacular and emblematic' reptiles The Galapagos Islands, which provided impetus and inspiration for Charles Darwin's seminal work, "On the Origin of Species", are home to unique populations of reptiles. Since the time of man's first visit in the 16th century to this crucial incubator for evolutionary theory, the islands' native plants and animals have faced grave challenges, including severe pressures...

Hybrid plants are growing bigger and more vigorously than their parents because they're more active during the day, U.S. researchers reported. University of Texas-Austin researchers said their study could mean new methods to increase biomass for biofuels and seed production for both animal and human consumption, the researchers said in university news release. Researchers said it's long been known that hybrid plants are more vigorous than their parents because they have more biomass and...

Although research has linked inbreeding with elevated rates of deformity in a wide variety of animals, a new study finds it plays no part in the high incidence of malformation among salamanders. Purdue University researchers recently examined 2,000 adult and juvenile salamanders and found that 8 percent had visible deformities, mainly consisting of missing, extra or dwarfed digits (equivalent to fingers and toes). That is double the rate of malformation found in newts, a related amphibian,...

REYKJAVIK, Iceland, Oct. 13 /PRNewswire-FirstCall/ -- Scientists at deCODE genetics today report the discovery of common versions of two single-letter variations in the human genome (SNPs) that confer risk of basal cell carcinoma (BCC), the most common cancer among people of European ancestry. Unlike the four sets of SNPs previously found by deCODE to confer risk of BCC and cutaneous melanoma, those reported today are not linked to fair pigmentation traits that also make certain people...

By Wilson, David Sloan Wilson, Edward O The process known as group selection was once accepted unthinkingly, then was widely discredited; it's time for a more discriminating assessment Is evolution a team sport, or is the contest for survival played out strictly between individuals? There's no question that natural selection acts on individual organisms: Those with favorable traits are more likely to pass along their genes to the next generation. But perhaps similar processes could operate...

SCOTTSDALE, Ariz., Sept. 8 /PRNewswire/ -- Two Scottsdale businesses Saturday (September 13) inaugurate what they believe to be the first public wellness workshop series to allow people to explore the intersection between personal genomics and individual health. "DNA and Your Health" is a half-day seminar at New Vision Spiritual Growth Center taught by two experts in their respective fields. They are Dr. Anne Marie Fine, a naturopathic primary care physician, and Dr. Donald N. Yates,...

By Domingues-Montanari, Sophie Subirana, Isaac; Tomas, Marta; Marrugat, Jaume; Senti, Mariano BACKGROUND: Environmental and genetic factors contribute to the development of complex diseases such as myocardial infarction (MI), the leading cause of death in men and women. Women develop MI approximately 10 years later than men, a difference that could be explained by the genes coding for the estrogen receptors. Single nucleotide polymorphisms (SNPs) in the ESR2 gene may affect susceptibility...

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...
