These are genetics terms that refer to which Filial generation the puppy is from.  So F1 means First Filial Generation and that means first cross of two pure bred lines.  In the case of Goldendoodles or Bernedoodles it means the puppy is 50% of each of the parent breeds.  “B” refers to a back cross to one of those parent breeds.  So an F1b is that 50/50 dog mated back to one of the parent breeds.  In the case of a goldendoodle that means 25% golden Retreiver and 75% poodle.  I will attach a handy chart that will explain the later generations.
