Lawrence LeBlond for redOrbit.com - Your Universe Online In a world that´s more than 4 billion years old, humans have only existed for a fraction of that–roughly 200,000 years. In those 200,000 years of existence, not a lot is known about genetic mutation until we close in on the last 5 to 10 thousand years. It is within that time that researchers believe nearly 75 percent of gene mutations have occurred, making our DNA distinctly different now than it was way back when. This...

Genes are being tested for roles in most conspicuous variations among dogs From the Dachshund's stubby legs to the Shar-Pei's wrinkly skin, breeding for certain characteristics has left its mark on the dog genome. Researchers have identified 155 regions on the canine genome that appear to have been influenced by selective breeding. With more than 400 distinct breeds, dogs come in a wide range of shapes, sizes, fur-styles, and temperaments. The curly-haired toy poodle, small enough to sit in a...

Scientists believe they have the answer to why the Chinese Shar-pei dog breed has a wrinkled appearance. In the analysis of ten pedigree dog breeds, scientists have discovered 155 unique locations in the animals' genetic code that may play a role in giving a dog its distinct appearance. In the Shar-pei, researchers found differences in the HAS2 gene which makes an enzyme known to be important in the production of skin. Joshua Akey, from the Department of Genome Sciences at the University of...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
