Well, here's my thinking. Poodles are one breed, not three different breeds. If you mate a miniature with a toy, what do you get? If the offspring grows to less than 10", it's a toy. If it's between 10" and 15" inches, it's a miniature. It's just like mating a tall person with a short person - the offspring might be short, tall, or in between, but it's not a different type of person, any more than toy is a different type of poodle. Again, they are all the same breed, just different sizes. There may be some correlations between size and other traits (similar to what I was saying in the other thread), but those don't define mini or toy (or standard for that matter).
