A three-factor cross involves three different genes or traits, and each gene has two possible alleles. This means that there are 2 x 2 x 2 = 8 possible gamete combinations for each parent. When these gametes are crossed, they can produce 8 x 8 = 64 possible offspring genotypes, which need to be shown in a Punnett square. Therefore, the answer is D, 64 boxes.
