Titan's DNA Results & the White Spotting Gene
White Spotting Gene
The White Spotting gene is a little different in that it does not effect PIGMENT, it removes PIGMENT altogether. This is NOT the same gene that produces solid white. The White Spotting gene is responsible for what is commonly called "Splash Coat" and/or "Pibald". When you look at the nose and lip PIGMENT, you will notice that it is NOT "liver" but rather more of a "pink" - similar to what you would expect to see on an albino. Going back, the White Spotting Gene REMOVES PIGMENT. This effects the TYPE and AMOUNT of PIGMENT in the eyes. NO PIGMENT = BLUE eyes

Below is Titan. He is a purebred Alaskan Malamute with Blue eyes. Due to the drastic effect of the White Spotting Gene, the pigment was also removed from his eyes. His solid white sister has amber eyes as her eyes were also effected, just not to the extent of Titan's. There is also another breeder who had a red puppy born with one blue eye, and one green eye due to the White Spotting gene. This is NOT the only gene to effect eye pigmentation. The diluting gene and red gene both effect eye pigmentation.
For EDUCATIONAL purposes, we did submit Titan's DNA to prove he is purebred. While we had no doubt, this is such a rare occurrence, we wanted to provide as much education, both for ourselves, and others, as possible.
One final thing I would like to mention, is that Titan is just our beloved baby. YES, the AKC lists blue eyes as a disqualifying fault - to clarify, disqualifying from the SHOW RING. Given it is a disqualifying fault, that in itself proves even the AKC recognises this can happen. I contacted the AKC and they confirmed that Titan is eligible for registration, but he would not be permitted in show. We were fine with this as we breed for working dogs, with the Eskimo standards as a guide.
Also, there are exactly 3 pages you will see Titan's eye colour mentioned. This page, the main Eye Colour page, and the Colours & Patterns page. All three pages are for education. You will never see mention of his eye colour anywhere else. Why? As rare as it is, we do feel the need to attempt to highlight his eye colour as some perceived sell tactic. We do NOT charge more for his puppies. We are not attempting to breed blue eyed puppies. Our price varies slightly with a couple of our pairings, due to the lines. We NEVER charge more based on gender, coat style/length, coat colour, pattern, or eye colour
