Question

Two genes (R or r) and (D or d), each with a dominant and recessive allele, are

inherited independently of each other. Which of the following combinations
could result in gametes of a plant with an Rr Dd genotype?
A. RD and rd
B. DR, Dr, Rd, dr
C. DD, Dd, dd, RR, Rr, rr
D. Rrand Dd

Answer 1

B. DR, Dr, Rd, dr

Step-by-step explanation:

This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.

Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:

DR, Dr, dR, dr
