My guy's is a lot like MM's mare. I've never seen one split the other way either, sounds cool. I will get a pic posted when I get back in the house. I think mine wanted to be a crop-out but didn't make it lol! He's solid bay with socks, star & snip but he also has ermine spots in his socks. Yep, he's weird :) Posted via Mobile Device
I don't know if there is a technical term or not...we've always called Dynasty's his boo-boo :) I think they are pretty cool myself! He's yet to pass it on to one of his babies, I always kinda hope he will though!
I do believe the splashed white pattern is the only pattern that causes any form of blue eyes. There is some question as to whether frame potentially causes it, but basically any horse ever tested with blue eyes has tested positive for splash. You can't test for frame, hence the unknown question as to whether it can also cause blue eyes. They would have to basically have a horse test negative for splash before they could definitively say frame (or any other pattern) causes blue eyes, and I don't believe that's happened yet.
And yes, when you see a solid horse with blue eyes, it's "hiding" the splash gene and genetically is able to produce/sire a pinto as well.
