The Secret of Dog Genetics
Dog breeding is really popular, lots of new breeds has been discovered for many years and still growing these days. But the true secret of this amazing dog genetics transformation has been revealed. A genome scientists from the University of California said he found dogs an intriguing research subject because generations of breeding have led them to have more diversity than any other mammal species. And they are very similar to humans in the way their body works and the illnesses they can develop.Human and dogs have the same gene called HAS2, which is important in forming skin and people with mutations in the gene develop wrinkled skins. The secret to dog breeding has been cracked open, and genome scientists are using artificial selection in dog breeds to explain how natural selection works in the human population. There are now close to 400 breeds of dogs worldwide and because of this discovery its going to get bigger.
The scientists also added that dogs are easier to study than humans because there is a restricted gene flow. Its because the extensive information, such as pedigrees, have been kept. These kinds of records help determine when a particular gene type begins to emerge in a particular breed, making mapping dog genetics easier.
