if you cross an F2 back to the F1 parent, you will be more likely to recapture the characteristics of the F1 when the new F2 is grown out, correct? and then if you do it again... even more likely? etc

It is called recurrent backcrossing. Each generation you select for the few dominant genes of the parent B that you want to keep and cross it back to the parent A which you want most of the genetic background (or each two generations for recessive genes)
