AM I getting this right? Biology GCSE refresher please!!

In simple terms, if I raise F1s from my F0 (95%> Amm) and these F1s are open mated, drones of these F1s will retain their mothers genetics. As the F0 is II, can I assume that the F1 drones will be 95%> Amm with the same traits as the F0 or am I getting this wrong?

They will be whatever she is Jeff.

Which in the case of controlled mating of the F0 should give good traits and the same level of purity.
