Wrinkle Genes

Scientists have found the gene behind the wrinkles of the Shar Pei dog breed. It was a gene which is known to make an enzyme important in the production of skin. Thus, more skin than the amount which seems enough is produced, giving the Shar Peis their wrinkles.

In fact, a lot of research is made on dog genes. The many different dog breeds from pure bred dogs make it easy for scientists to discover the individual role of each gene. This is but one example of how we dogs are essential for the modern human.
