This book is based on our research paper published on Sept, 20, 2018 to PLOS ONE - an online peer-reviewed scientific journal published by the "Public Library of Science."

The paper was purposely submitted to a journal that is "open access", meaning that readers are not required to pay a monthly, yearly or a one time fee to view and download the paper. The paper may also be freely shared. This was done specifically to make this information readily available to all who are interested - not only to researchers but to owners and breeders, those who deal with the inheritance of Merle through generations of pedigrees.

The paper may be viewed by following the link provided below.
My book will expand upon information in the research paper, approached in a way that it is easy to understand and follow.
