Initially, many people are confused
by the use of terms such as F1, F1b, F2, etc... These are
genetic terms referring to how the two breeds were crossed.
There are additional terms to describe the breed such as LO1,
LO1pp, AL1, AL2. Basically, the LO refers to Labradoodle Origin
(meaning a North American Labradoodle) and the AL refers to
Australian Labradoodle. I will talk about the differences
between Labradoodle Origin and Australian Labradoodles a bit
later.
An F1 (or first generation) is a Poodle bred to a Labrador
Retriever or a Golden Retriever. The resulting puppies are
50% Poodle and 50% Retriever.
An F1b is also referred to as a Backcross. In this case,
an F1 is bred back to a Poodle. The puppies are 75% Poodle
and 25% Retriever. To make things more confusing, an F1b is
also referred to as an F2.
An F2 is a second generation, an F3 is a third generation,
and so on. These pups would be produced by breeding dogs together
that have multiple generations of Doodle in their background,
thus the shortened term Multigen.
Except for the F1's and F1b's, there are a lot of combinations
that can be produced. The higher percentage of Poodle doesn't
necessarily produce more 'Poodley-looking' puppies but it
does consistently produce non-shedding, allergy-free coats
in our litters.
The following charts can help you visualize the differences
when different combinations are used:

There are quite a few different
combinations for an F2 Doodle and many more for F3's, F4's,
etc.
Here are only 2 examples to keep it
less confusing.

As you can see with the F2s, there
is quite a difference between the percentages of the two examples
given, so it is important to know the parents specific lines.
The 1st example can have questionable coats with regard to
shedding. The 2nd example would be much more reliable, especially
if the 1st parent is non-shedding or low-shedding to begin
with. These examples are just a primer in the world of Doodles.
Although there is not yet an offical governing/registration
organization for Goldendoodles we use the same terminology
for them as well.
