What is the difference between an F1 cockapoo and an F2 cockapoo?

I keep hearing it but I never understand what's the difference, I mean they're both cockapoos, right?
Answers:
The F1 generation is pure cocker to pure poodle and the results are relativly predictible and consistant as to apperance qualities such as shedding. F2 is cockapoo to coockapoo and not very predictable.

Cockapoos are considered 1st generation (F1) if the parents are pure cockers and pure poodle. Cockapoo to Cockapoo is 2nd generation (F2) and progressing F2 to F2 begets F3 - etc. For recording purposes we take the lowest F factor to 'label' the progeny. Thus and F6 to and F2 would be considered an F3. They are still cockapoos as long as the origin was 1/2 cocker and 1/2 poodle and nothing else has been mixed in along the way, and it stays cockapoo to cockapoo without adding back in any poodle or cocker.
