DNA private color Study for Sable vs Fawn
October 3, 2015...posted on FaceBook
Scroll down to see participating dogs.
 
DNA STUDY-ENGLISH BULLDOGS PLEASE PARTICIPATE: I would like to conduct a DNA study if I can get enough people to participate. Although this is not officially sanctioned by my Genetics Lab, I will be sharing my findings with them to get their opinions. We have done this before & our findings were published by the geneticist years ago.

I am thinking that their is a difference between the DNA of a True Sable & a True Fawn. Would like to see if I am correct or not.

My thinking is that the Sable, which tends to show tri points when younger is ayat at Agouti, while the True Fawn is ayay at Agouti and never show tri points.

DNA RESULTS: SABLE VS FAWN
 MUCH Thanks to Miriam Acosta, Derek Darr, Kirsty Tollady, Colin Fashoni, Rod Triline, Steve Novy, Katherine Colvin Ferguson, Jodie Weech, Mark Barnes, Jamin Smith, Sonya Wagner Ivester, Sheri Mccormick-Lewis, Lynnette Meadows, Tonya Springer Jackson, Crystal Guerrero, Susan MacKay Pontius, Cheri Schweitzer, for participating. I hope I did not leave anyone out!

Results from this study are that Sable EB's that show tan points &/or have dark etching, DO carry one [at] & are ayat in their dna. A TRUE Fawn will not show sable hairs, tan points, or dark etching & will be ayay in their DNA.
 
From the Geneticist: Because it has not been proven, I cannot say it is impossible for an ayay (agouti) dog to show tan points, but it would be highly unlikely.
 
Thanks to all the Breeders who Participated!!
