13 Black coat color (B) in cocker spaniels is dominant to white coat color (b). Solid coat pattern (S) is dominant to spotted pattern (s). The pattern arrangement is located on a different chromosome than the one for color, and its gene segregates independently of the color gene. A male that is black with a solid pattern mates with three females. Indicate the genotypes of the parents. a) The mating with female A, which is white, solid, produces four pups: two black, solid, and two white, solid. b) The mating with female B, which is black, solid, produces a single pup, which is white, spotted. c) The mating with female C, which is white, spotted, produces four pups: one white, solid; one white spotted; one black, solid; one black, spotted.

Expert Solution
Step 1

So according to the law of assortment from Mendel's in dihybrid cross . This law states that assortment of genes of one pairs is independent of the other pair at the time of gametogenesis. Each pair of contrasting character behaves independently and bears no association with particular character.
