Graying out, i figure this will be interesting to show.

So basically my cousins boyfriend bought Rocky from my dad (thank god as my dad shouldn't be allowed to own horses but I won't go in to that)
Anyways I have photos of rocky growing and his colour changes, His dam is an appaloosa and his sire is a dark bay tb x cob.
Rocky has just turned 5 (i think, could be 6) So what do you guys think, potentially turning to white gray? The most noticeable colour change is on his face. Feel free too post you're own graying out horses would love too see it.

That is my favorite color horse. I had a mare that color when I was in high school. I bought her when she was 3 and sold her at 5 so I didn't get to see her color change but imagine she is very light by now. She would be about 17-18 now.

Yes he will eventually grey to white IMPO.

If I'm not mistaken all greys go white with time.

His body is very dark so it'll take him a while to turn white.

I think she means if it will be more of a horse with flea bites or pure white or something.

All greys go white with time or some develop fleabitten coats but its hard to know which for sure.

I'm not a grey fan, but I must say it has been interesting watching our chestnut tobiano foal turn different types of grey as he ages. He is 6 years old this year and it wouldn't surprise me if he was pure white by the time he was 10.

Homozygous gray horses are far more likely to end up pure white. Heterozygous gray horses are far more likely to end up with a large number of fleabitten specks.

Until they isolate the gene causing flea bitten, then I think it is premature to say that. There is so much more going on with grey - how do full siblings grey at different rates etc.

Before the test for grey was developed, it was believed that homozygous greys always greyed faster than heterozygous greys. That has been proven wrong since the grey gene has been isolated.

Off the top of my head, the only tested grey horse I could think of was Winner from True Colors. He looks flea bitten, and is homozygous.
