F1b.  This is a puppy that is 3/4 Poodle and 1/4 Wheaten... theoretically...  There is always a chance that the characteristics they inherit will be more of one breed or the other.  Our Whoodle still has a very wavy coat, so the chance of having a very curly coat is smaller.  We can see curlier coats at a very young age.  These are great puppies giving you that smaller size option.  They will mature more around 17lbs.
