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....

Personal Genetic Data Exposed To Security Vulnerabilities
2013-01-18 03:39:51

redOrbit Staff & Wire Reports - Your Universe Online Armed with nothing but a laptop and an Internet connection, researchers from the Whitehead Institute for Biomedical Research at MIT say they were able to uncover the identities of almost 50 people who donated DNA to genetic research studies. Their work raises series questions about the privacy practices used to safeguard personal data for volunteers in genomic research. The results of their so-called “vulnerability...

Study Finds Genetic Trail Linking Early Australian Inhabitants With Indians
2013-01-15 10:26:29

Brett Smith for redOrbit.com - Your Universe Online A new study in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS) from geneticists at the Max Planck Institute in Leipzig, Germany could lead to a rewriting of the cultural history of Australia. The researchers say that a recent genetic analysis shows evidence of a substantial flow of genes running between the Indian and Australian populations about 4,000 years ago. "Interestingly, this...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

MOUNTAIN VIEW, Calif., Dec. 13, 2012 /PRNewswire/ -- 23andMe, the leading personal genetics company, today announced the availability of Ancestry Composition, a new feature that provides state-of-the-art geographic illustration of an individual's ancestral origins. Using 22 reference populations, the feature indicates what percent of a person's ancestry comes from various regions around the world. The analysis includes DNA inherited from all ancestors on both sides of the family. The results...

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...
