Individuals of a particular species generally differ from one another. We are clearly most adept at recognizing members of our own species, although dog and cat owners will be ready to confirm that their pets look unique. Differences within species relate to characteristics such as size and shape but also to color: it is not only humans that show a wide range of skin pigmentation. Nevertheless, the cause of the variation in skin color in animals has remained largely a matter for conjecture....

Rice computational study tracks E. coli cells´ regulatory mechanisms Environment is not the only factor in shaping regulatory patterns – and it might not even be the primary factor, according to a new Rice University study that looks at how cells´ protein networks relate to a bacteria´s genome. The Rice lab of computer scientist Luay Nakhleh reported in the Proceedings of the National Academy of Sciences that when environmental factors are eliminated from an...

It's In The Genes: Europeans Have Been One Big Family For Past Thousand Years
2013-05-08 07:34:50

Lawrence LeBlond for redOrbit.com - Your Universe Online If there is one thing you can say about families, it is the larger the better. And by looking at genetic data of people from Ireland to the Balkans, researchers have found that Europeans are one big family, and have been for the past thousand years. Graham Coop, a professor of evolution and ecology at UCDavis, and Peter Ralph, a professor at University of Southern California (USC), published a recent study of the genetics of...

DNA sequenced from ancient skeletons sheds light on how modern European populations formed An international team of scientists, including Dr Paul Brotherton from the University of Huddersfield, reveal that events after the initial migration of farmers into Europe had a major impact on the modern gene pool. The paper, published in Nature Communications, investigates a major component of the maternal population history of modern Europeans by focusing on haplogroup H mitochondrial genomes...

Paternal Cues Heavily Influence Mate Choice In Mice
2013-03-28 16:35:39

Max-Planck-Gesellschaft Hybrid offspring of different house mice populations show a preference for mating with individuals from their father's original population Mate choice is a key factor in the evolution of new animal species. The choice of a specific mate can decisively influence the evolutionary development of a species. In mice, the attractiveness of a potential mate is conveyed by scent cues and ultrasonic vocalizations. Researchers from the Max Planck Institute for Evolutionary...

Ancient Human Skulls Show Evidence Of Prevalent Inbreeding
2013-03-19 15:25:55

Brett Smith for redOrbit.com - Your Universe Online Although it is considered completely taboo in most modern societies, an ancient human skull found in northern China suggests inbreeding could have been prevalent among ancient peoples around 100,000 years ago, according to a report in the open access journal PLoS ONE. The skull — which was found at Xujiayao, a mountainous excavation site several hundred miles from the Mongolian border — contained an enlarged parietal...

Research discovers that whether a female butterfly will mate with a male depends on the quality of his sex pheromones The mating success of male butterflies is often lower if they are inbred. But how do female butterflies know which males to avoid? New research reveals that inbred male butterflies produce significantly less sex pheromones, making them less attractive to females. The research was published today in the journal Proceedings of the Royal Society B. If animals (and humans)...

Researchers led by biostatistician Andrea Foulkes have applied sophisticated statistical tools to existing large databases to reveal substantial new information about genes that cause such conditions as high cholesterol linked to heart disease Recently, large studies have identified some of the genetic basis for important common diseases such as heart disease and diabetes, but most of the genetic contribution to them remains undiscovered. Now researchers at the University of Massachusetts...

An article recently published in the Journal of Mammalogy, Volume 94 Issue 6 focuses on the struggling Florida manatee population and analyzes the factors pertaining to their decline. (PRWEB) January 29, 2013 Journal of Mammalogy — There is a better than 49 percent probability that the Florida manatee population will fall below 500 individual animals in the next 100 years, according to one analysis. One of the factors that can drive population decline is a lack of genetic diversity....

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...
