First question, yes you'd get autos.
Second question, the accepted norm is no autos in F1s of that pairing...from personal experience tho if the mother is auto and father reg, you have a lot higher ratio of autos in F1s. If the father is an auto and mother is reg, then you get very few autos in F1s.
If you do the mother reg x auto father, the accepted norm is youd have to breed further until you got real autoflower
Source:currently running F1s (auto mom x reg father) 16/16 autoflowered in 18/6 light schedule.
