Why is Fido furry?

     vetHere is something that I find very interesting. According to a new report , researchers have just discovered that nearly all the differences in the coat types of purebred dogs result from variations in just three genes and It’s not so much the genes themselves, but how they work together that makes the difference.

    The researchers studied variations in the DNA of more than 1,000 dogs from 80 breeds. The results were then compared to descriptionsof various coat types.   The findings, which appear in the online edition of the journal Science, could have implications for humans. Dr. Elaine Ostrander of the National Human Genome Research Institute says the same approach to looking at genes could help pinpoint the multiple genes involved in complex human conditions, such as cancer, heart disease, diabetes and obesity.
