If you were to mix a black and white tobiano stallion with a black and white tobiano mare, will you pretty much be guarenteed a black and white tobiano foal?
Without knowing whether or not one of them is homozygous for tobiano, or if either of them is a red (e) carrier, you have about a 70% chance of black tobiano. There is also a possibility for black (about 23% chance), chestnut (1.5~%), or chestnut tobiano (4.7~%)
not sure on the tobiano but the black yes for sure.....I didn't know there was a test for the tobiano......thought it was just the pattern? Humm the things we learn everyday. So how would I know if they are for sure?
One way to kind of guess if a horse is homozygous for tobiano is if they have "cat tracks". Little black (in your case) spots as well as the larger patches of black in their pattern.
Like this stallion displays, who happens to be homozygous for tobiano.
It's not a surefire way of knowing, but a lot of homozygous tobianos have them.
I know there are, which is why I said it wasn't a surefire way to know if the horse is homozygous, but since a large majority of homozyg. tobs do have them it could possibly be an indicator.
Hummmmm.....I know my girl doesn't have any spots (cat tracks).....I don't believe he does either cuz they look almost identical to each other. So if they're not then what can the differences be? Just the pattern?
There is no way to tell by looking at the pattern if a horse is homozygous for Tobiano. In fact, I have seen a filly that is completely solid that has tested **** for tobi. The only way to tell if she is **** or hetero is to test her.
