This is a photographic essay demonstrateing the effect of the greying factor upon the brindle gene.
   

Aaron's coloration at birth was red/gold brindle and white parti-color. He was 16 months old when this photo was taken. He appears to be a red/gold and white parti-color. The length of the hair 'hides' his brindle pattern.
 
This is Aaron at five years old. The greying factor working upon his brindle gene creates what appears to be a black and white parti-color dog.
   

Here's a photo of Frankie, on the left, with two of his siblings, Eve and Tony. The puppies sire is Aaron.
Frankie's brindle pattern is very evident in this photo.
   

Here's Frankie in long coat, pictured with Ali. Frankie appears silver in this photo.
   

This is Allie, an Aaron daughter, as a puppy. She appears to be a dark gold sable, however she is a red/gold brindle.
Allie, the day she finished her Championship. It's hard to tell from this photo, but by then she was a beautiful color of pewter. Again, the action of the greying factor on her brindle gene.
   

This is Robby, Allie's litterbrother. He appears to be a black and white parti-color. He's not. He's brindle with a greying factor.
   

This photo of Moon, an Aaron granddaughter, shows her red/gold brindle pattern.
And here she is two years later, after the greying factor had some time to work its 'magic'.
   
Aaron's dam, Kermit - Byrnwood's Anastasia - introduced the brindle gene.
She is from 'old English' breeding. This gene was prevalent in that gene pool.
   

Notice her brindle pattern.
