In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall andsmooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny

a. The genotypes of both plant A and plant B are DdPp

b. In plant A, Gene D and Gene P link as cis configuration

c. In plant B, Gene D and Gene P link as cis configuration

d. In plant A, Gene D and Gene P link as trans configuration

e. In plant B, Gene D and Gene P link as trans configuration
