Quantitative Inheritance
16. FRUIT WEIGHT IN ORANGES
Shown below are the results of a breeding experiment designed to test the inheritance of fruit
weight in oranges. The initial cross was between two true-breeding lines, Inbred X and Inbred Y,
which were grown under identical environmental conditions and produced fruit weighing 24 and
32 grams, respectively.

Determine the number of gene pairs contributing to fruit weight that are segregating
in this cross. Clearly show the method you use.
b. Designate these genes with letters (A, B, C, etc.) and give possible genotypes of Inbred
X, Inbred Y, and the F, hybrid.
Inbred X:
Inbred Y:
c. A plant has all nonadditive alleles. How much will the fruit from this plant weigh?
