Yeah mate you can cross anything you like
so basically all depends on your phenotype selection and what way the plant you use leans towards each parent, you will find some more towards the mothers genes and others leaning towards the father.
In a basic scenario we make a cross and its 50/50 towards each parent, this makes it 50% Mother and 50% Father, say we hit 2 mothers with the male we would have 50% Mother 1 50% Father and on the other 50% Mother 2 and 50% father, then taking a plant from each of those and made a cross, we would then have 25% Mother 1 25% Mother 2 and then 50% of the fathers genetics
hope that makes sense
