You are given two populations of true-breeding tomato plants with two traits that sort independently. Using the multiplication rule, how many of the F₂ progeny would you expect to have a recessive phenotype for both traits? A)9/16 B)6/16 C)3/16 D)1/16

The multiplication rule states that the probability of two independent events both occurring is the product of their individual probabilities. For two traits that sort independently, if each trait has a recessive phenotype probability of 1/4 (since the plants are true-breeding, implying a simple Mendelian inheritance with a dominant and recessive allele for each trait), then the probability of an offspring having both recessive phenotypes is 1/4 * 1/4 = 1/16.
