In July 2017, Embark worked with Cornell University to test more than 6,000 dogs of various breeds in order to identify the genetic mutation that causes blue eyes, which was the first research of its kind to be conducted on non-humans. Dog owners conducted DNA tests from Embark, completed online surveys, and Embark and Cornell analyzed the data.
Waardenburg syndrome is a group of rare genetic conditions characterised by at least some degree of congenital hearing loss and pigmentation deficiencies, which can include bright blue eyes (or one blue eye and one brown eye), a white forelock or patches of light skin.
Among dogs, complete heterochromia is seen often in the Siberian Husky and few other breeds, usually Australian Shepherd and Catahoula Leopard Dog and rarely in Shih Tzu. Horses with complete heterochromia have one brown and one white, gray, or blue eye—complete heterochromia is more common in horses with pinto coloring.
Siberian Huskies, Australian Shepherds and Weimaraners are known for their blue eyes, but you can also find Bulldogs, Cardigan Welsh Corgis and Dalmatians with baby blues. This trait is genetic ...
Blue eyes are a rare physical trait that make for a very striking appearance. The post 12 Dog Breeds with Beautiful Blue Eyes appeared first on Reader's Digest.
Siberian husky eyes. Blue eyes are common in huskies and they are certainly captivating. But having a husky with two different color eyes is also just as common. This is known as heterochromia.
Blue eyes in dogs are often related to pigment loss in coatings. The merle gene results in a bluish iris, and merle dogs often have blue, walled, or split eyes due to random pigment loss. Some genetic variants cause Heterochromia iridum. [68] The second way blue eyes can appear is when a dog has a lot of white fur on the face.
Red and white Siberian Husky with heterochromia. The American Kennel Club describes the Siberian Husky's eyes as "an almond shape, moderately spaced and set slightly obliquely". The AKC breed standard is that eyes may be brown, blue or black; one of each or particoloured are acceptable (complete is heterochromia). These eye-color combinations ...
