Only a few variations/types of overo are testable. Just like sabino and DW, there are more than just the ones they test for. There are others that won't show up on a test, and I'm sure there's even a few that haven't even been discovered yet.
I get that but frame overo has always been frame overo. I have never heard of any horse this definitively frame testing as nn. This opens a whole new set of doors into LWO if it's true. I wouldn't even have tested these horses and certainly would have never bred them to any other frame overos.
Mom as a baby with dam who also shows as frame and apparently DID test nO for frame.
Apparently a color expert told her they were frame overos and to test for LW. But what color expert would tell you to test for something visible?
The discussion being had is because some people think that a horse can be frame overo and not "carry" LWO. I'm trying to explain it's the same thing - the color itself is the deadly mutation in homozygous form. Posted via Mobile Device
Interesting. Did they show UC Davis the pictures of the horses? Because I have a feeling that they would want to know if a horse that phenotypically appears to be the definition of frame came up negative twice, they'd want to look into it. Right after they released the splash tests, they were getting responses from people who had horses that looked like textbook splash horses that were negative for all three mutations so they requested further contact from those owners to research further mutations.
