b. 0%

c. 0%

d. 0%

e. 100%

f. 0%

g. 0%

Note: Answers are given assuming that hhRD = hhDD

Explanation:

a. The cross, HHdd x hhDD is a dihybrid cross involving two traits: fruit colour and fruit shape

2. Gametes produced in the cross are given below:

for HHdd= Hd and Hd

For hhDD = hD and hD

Offspring produced in the cross:

All HhDd, which represents white and the flattened disc-shaped fruit white since They are both dominant characters.

b. Percentage of the offspring from this cross expected to have the HHDD genotype = 0%

c. Percentage of the offspring from this cros expected to have the hhDD genotype = 0%

d. Percentage of the offspring from this cross expected to have the HhDd genotype = 0%

e. Percentage of the offspring from this cross are expected to produce white and disc-shaped fruits (HHDD or HhDD or HhDd) = 100%

f. Percentage of the offspring from this cross expected to produce white and spherical fruits (HHdd or Hhdd) = 0%

g. Percentage of the offspring from this cross expected to produce yellow and disc-shape (hhDD or hhDd) = 0%
