Given below are a few statements on mapping populations and marker-assisted selection (MAS): A. MAS can be used to eliminate undesirable genotypes early in the breeding program by screening plants at the seedling stage. B. In backcross breeding programs, breeders use molecular markers to select against the donor genome to accelerate recovery of the recurrent parent genome. C. Among different types of mapping populations, F2 and F2:3 populations are immortal populations. D. Near Isogenic Lines (NILs) can be produced by repeated self-pollination of F1. Which one of the following options represents the combination of all correct statements?
