In some cases it is much easier. If a bay stallion sires one chestnut foal you know that he carries the chestnut gene in addition to the bay. This can happen with the first foal.
So it kind of depends.
By the way the gray gene is carried on horse chromosome 25. Now the trick is to figure out what else is on that chromosome. Folk wisdom was that gray horses weren't all that speedy, but could run all day, suggesting that there are stamina influences lurking around on this chromosome.
Anyone want to come up with horses to prove/disprove this theory?
Grey horses off the top of my head are Native Dancer, Grey Dawn, Vigors, Gato Del Sol, Relaunch, Mahmoud, Silver Fog, Icecapade, Shenanigans....
Differences? Similarities?
