I seen though in your thread..the stallion you have considered for breeding if you do...has he been tested? If he is - for frame it shouldnt matter if yours carries it...I believe to get a LWO both parents must at least be heter and carry the frame gene.
I'm just starting learning more about them myself;I knew they were out there,but didn't really know their characteristics,ect. It's really quite extensive,way more to them then I first thought there to be.There's a whole world of learning to be done in the white color patterns alone! Lol
Well I know this..my gelding is Tobiano/sabino and I guess frame since his test was nO....and both my mares are nn so there is a 50/50 of the foals being nO and nn......so who knows...although unplanned breedings and I now excited to see what we end up with.
