Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...

Historical records are often used to learn about ancestry but a new approach, using genetics, is currently being applied. In a recent study, published in PLOS Genetics, scientists from the Stanford University School of Medicine and the University of Miami Miller School of Medicine compared patterns of genetic variation found in populations in and around the Caribbean. They were able to discern an influx of European genes into the native population that occurred within a generation of...

Those of us who want to learn about our ancestors — who they were, where they came from and how they mingled (or didn't) with others around them — often turn to historical records or elderly family members for answers. But a new study by researchers at the Stanford University School of Medicine and the University of Miami Miller School of Medicine indicates that the answers can also be found within our own genes. The researchers compared patterns of genetic variation found in...

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

Brett Smith for redOrbit.com - Your Universe Online It can be puzzling sometimes when someone else finds the taste of your favorite food to be disgusting, but research has shown we all perceive the taste of various compounds differently. A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the...

The latest study was published online in Nature Genetics Coding variants in immune disease-related genes play only a small part in the overall genetic risk for psoriasis, according to a new study led by Anhui Medical University and BGI. This conclusion is strongly supported by their investigation on the contribution of functional coding variants to psoriasis in 21,309 Chinese individuals. In such a large-scale investigation, researchers only discovered two independent low-frequency...

The unique genomic signature could serve as a research model for founding events Researchers at the Sainte-Justine University Hospital Center and University of Montreal have discovered that the genomic signature inherited by today's 6 million French Canadians from the first 8,500 French settlers who colonized New France some 400 years ago has gone through an unparalleled change in human history, in a remarkably short timescale. This unique signature could serve as an ideal model to study...

Genetic Evidence How Man Migrated To Europe

Brett Smith for redOrbit.com - Your Universe Online Humans emerged en masse from Africa thousands of years ago, but scientists still aren’t sure about the exact routes they took as they set out to populate the planet. According to a new DNA analysis from an international team of researchers, human expansion most likely occurred after the Last Glacial Maximum, between 26,500 and 19,000 years ago, and the Neolithic Era, approximately 12,000 years ago. The researchers reached their...

Two women have the same genetic mutation – an abnormal BRCA1 gene that puts them both at much higher-than-average risk for breast cancer – but only one woman develops the disease. Why? Michigan State University genetic scientists have begun to understand the mechanisms behind the phenomena. "It's been known for a while that genetic mutations can modify each other," explained Ian Dworkin, MSU associate professor of zoology. "And we also know that the...

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...
