Chapter 5, Problem 29P
A true-breeding strain of Virginia tobacco has dominant alleles determining leaf morphology (M), leaf color (C), and leaf size (S). A Carolina strain is homozygous for the recessive alleles of these three genes. These genes are found on the same chromosome as follows:
An F1 hybrid between the two strains is now backcrossed to the Carolina strain. Assuming no interference:
a. | What proportion of the backcross progeny will resemble the Virginia strain for all the three traits? |
b. | What proportion of the backcross progeny will resemble the Carolina for all the three traits? |
c. | What proportion of the backcross progeny will have the leaf morphology and leaf size of the Virginia strain but the leaf color of the Carolina strain? |
d. | What proportion of the backcross progeny will have the leaf morphology and leaf color of the Virginia strain but the leaf size of Carolina strain? |

Two pure-breeding lines of petunia plants are crossed. Line 1 plants grow to a height of 54
cm, and Line 2 plants grow to a height of 18 cm. Petunia plant height is controlled by three
genes, A, B and C. Line 1 has the genotype A₁A₁B₁B₁C₁C₁, and line 2 has the genotype
A2A2B₂B₂C₂C₂. Assume that genotype alone determines plant height under ideal growth
conditions and that the alleles of the three genes are additive.
