How does this work

Postby karenkarenn » Tue Sep 11, 2012 6:42 pm

Hello, For the most part I don't know too much about coloring but,
How would a Grey/roan Sire mate with a bay mare make a chestnut?

The gray sire only had a 50% chance of passing on his gray.
Chestnut is a recessive color so it "hides" under other colors. Both the stallion and the mare had an underlying chestnut gene to pass on and luck of the draw dictated the foal be a chestnut without gray. :)

Years ago I boarded at a farm that bred Quarter Horses

Their grey stallion kept popping out palomino's and buckskin's out of bay, chestnut and black mares and I couldnt figure out how that was possible

It wasnt until someone explained that grey isnt a "colour" - its a "modifier" hiding the true base coat colour, that I understood. He was palomino underneath the grey so always had the 50% chance of passing on the dilute gene, as well as having the 50% chance of passing on his own grey modifying gene

Wheelaway the stallion by Unbridled
Would you say that the underlined color is black?

Sadly it's virtually impossible to tell without seeing a photo of him as a foal. Black is uncommon in racing Thoroughbreds so I doubt it, but there's no way to know.
