Tobiano or Sabino?

Hello! I have wandered over from owning thoroughbreds to getting a fun APHA gelding. According to his papers he is Tobiano, as are both his sire and dam. But I have been perusing the internet and now I think he may have some Sabino in his genes.

So, for all you more knowledgeable in horse color genetice, especially paint colors, what do you think?

I don't have the best photos of him yet, but here's one from today. He does have white on his chin, some roaning around his spots, and brown "rings" around each chestnut (which I have never seen before).

Id say tobiano

I say Tobiano too. Handsome boy! Welcome to the forum!

I'd say Tobi for sure but from the pic I really can't the shadowing and other clues that might make me think Sabino as well. It could be the pic though.

He is tobiano and he does look to have sabino as well.

I am not sure, I just had to tell you I love the look of your horse!

Roany patches are a common tobiano trait, as well as sabino....got any other pictures of him? The white on his face could also be attributed to splash as well. He's a cutie.

I would say Tobiano but is also showing underlying sabino traits. The roaning,white on chin & under jaw.
Nice looking boy!

Tobiano, sabino, and perhaps frame too. Maybe also splash lol. Tobiano causes the white from the top downwards, sabino because of the chin white, splash because of the bottom heavy face marking, and frame from the way the white on his side seems to want to go horizontal instead of vertical.
