You would only pick a great female as the mother and you would want the traits she expressed that's why you are trying to bx2 in the first place. The second part about different results is true for the f2 cross but wouldn't 75% of the genetics be the choosen females genetics anyway? Not saying you won't get some differences but as long as they are not a bad trait (ie intersex or lanky ect.) the next cross (f3 backcross to one female) would reaffirm the mothers genetics to 87% regardless? And the last cross would again reaffirm the mothers genetics up to 99%Maybe for individual traits, I don't think that works for the plant as a whole?

I think yer gonna get different results per trait per male each time, AA male, Aa, male, aa male...
Yer polyhybrid mom can be AA Aa aa for each trait she is expressing too.
So whatever she is for whatever trait x whatever the male is that is used each time is gonna get you different results?
If the mother is a polyhybrid then yes more intense selection of the resulting seeds and that male would need to be selected based on the traits your breeding for. I agree. That's why poly hybrids would be alot more difficult to bx2.
It is always the same mother regardless for what you are crossing into. Not saying other traits might not be present. (wishful thinking probably but hopefully those traits would be for something like desease resistance and not something bad) lolThat is ALL dependent on the recurrent (mother as you put it) in the 1st place.
There's a post in here on backcrossing.

Still believe this to be one of the best methods to stabilize a trait or plant that will breed 99% true. (meaning less chance for multiple phenos.) And in most grows that are small is one of the best methods to breed seeds that will produce the same results everytime. Also to be able to pass those traits on every time in any new crosses. Meaning different strain crosses of different types.
