Gina’s White Hair

Gina’s summer coat has something weird going on: it appears to be roan.

As you can see, her coat is flecked with white hairs. It isn’t noticeable from a distance, but when you stand next to her, you can see it pretty clearly.

Now, whether or not Gina has always been this way is unknown to me. This year was the first time I’ve seen her summer coat. I don’t recall seeing white hairs in her winter coat in January, but I don’t know that I was really looking, either.

It seems entirely possible that Gina carries the sabino gene. Her maternal grandsire, Time To Explode was an usually colored stallion:

He’s by Explodent, who is also a sabino and is apparently known for siring colorful foals.

Makes me wonder if I should register Gina as Pinto breeding stock after all.

Good Breeding

The program added a couple of new horses this week, and one is a super-cute chestnut Thoroughbred gelding. I took the liberty of searching for him on Pedigree Query, as I am wont to do with all TBs I encounter. His parentage is nothing spectacular; it’s better than sweet, inbred Moe, but not as impressive as Gina’s. Take a look:

That’s Mr. Prospector on top and Affirmed on bottom. In my limited research, it appears that neither of these lines are known for producing anything but astonishingly competent racehorses. Which brings me back to my original mystery: why was G sold to a sporthorse breeder in Oklahoma as a two year old? 
Both G’s sire and dam were decent racers. Her sire, Look See won over $100,000 on the track and sired numerous stakes winners. Her dam, True Brilliance, earned a respectable $23,000. Gina has two full siblings, both mares, with no race record. Some of her half-siblings on her dam’s side have been fairly successful racehorses. The half-siblings on her sire’s side are too numerous to list (but you can see them here, if you want), but believe me when I say many of them are very good. 
Gina isn’t much of a lean, leggy Thoroughbred; she’s of the stout variety. Did her breeders see this in her as a two year old? Did they ever get her out on the track? Was she a giant, horrible brat they wanted to unload ASAP? How did I end up with such a mysterious horse?
