As indicated in the image below the dominant allele R confer

As indicated in the image below, the dominant allele (R) confers susceptibility to the Bt toxin, and a recessive allele (r) confers resistance to Bt. Suppose that a susceptible male mates with a resistant female. They have many offspring, a few of which are resistant to Bt. What is the genotype of the male parent, and what is the genotype of the susceptible offspring? (Assume complete dominance.) The genotype of the male parent is Rr and the genotype of the susceptible offspring is Rr. The genotype of the male parent is either RR or Rr and the genotype of the susceptible offspring is Rr. The genotype of the male parent is Rr and the genotype of the susceptible offspring is either RR or Rr. The genotype of the male parent is either RR or Rr and the genotype of the susceptible offspring is either RR or Rr. The genotype of the male parent is RR and the genotype of the susceptible offspring is Rr.

Solution

Ans: The genotype of the male parent is either RR or Rr and the genotype of the susceptible offspring is Rr.
