B)the laws of segregation.
C)the law of independent assortment.
D)crossing over.
E)chromosome aberration.

Crossing over is the only process that can produce a gamete with a combination of alleles that are not present in the parental chromosomes. This process, which occurs during meiosis, involves the exchange of genetic material between homologous chromosomes, resulting in new combinations of alleles. In this case, crossing over between the M and m alleles on the maternal and paternal chromosomes, respectively, would lead to the production of a gamete with alleles l, m, and N. The other processes listed (nondisjunction, segregation, independent assortment, and chromosome aberration) do not directly result in the production of new combinations of alleles.
