B)Independent assortment of the genes.
C)Crossovers between the genes results in chromosomal exchange.
D)Nonrecombinant chromosomes break and then re-join with one another.

Crossovers between the genes results in chromosomal exchange, which can cause recombination between linked genes. A mutation that causes one homolog to be different from the other homolog would not necessarily cause recombination, as the difference may not be located near the linked genes. Independent assortment of the genes would also not cause recombination between linked genes, as they are still located on the same chromosome. Nonrecombinant chromosomes breaking and re-joining with one another may cause recombination, but this is essentially the same process as crossovers between the genes.
