Coat Color in Greyhounds

When breeding a greyhound litter it is always exciting to see what colors the puppies are. With a few basic rules of genetics, the majority of the time colors can be predicted. Three basic colors are present in the breed.

Black

Red Brindle

and Red

BISS Ch Aryal Aroi Stoney Ridge CD TD RE NAJ SC

Dogs receive a color gene from each parent meaning if they receive a black gene from one parent and a red gene from the other the dog will be black. If they receive a brindle gene and a red gene the dog will be brindle.

Next comes the modifier genes. The first one is the dilution color. It is recessive so a dog must receive a dilute gene from each parent. If they only have one dilution gene the dog will a nondilute color. So the dilution gene on a black dog gives a

The dilution gene on a brindle creates a blue brindle

The dilution gene on a red creates a blue fawn

And last is the Parti gene. This gene allows only part of the base color to be expressed. Once again this modifier gene is recessive meaning the dog has to get the gene from both parents. If it only gets one it is a solid colored dog.

If the dilute gene is present it would be a blue and white parti color(no photo).

Brindle+Parti would be a red brindle(No photo)
if+Dilute would be a blue brindle parti

And lastly Red+Parti would be a red and white color

if+Dilute would be Blue Fawn Parti

This covers about 99% of the coat colors, some rarer colors such as liver or chocolate or EE Red are not covered but infrequently seen.
