Flower position, stem length, and seed shape were three charactersthat Mendel chose to study. Each is controlled by an independently assorting gene andhas dominant and recessive expressions as follows:
Trait Dominant Recessive
Flower position Axial (A) Terminal (a)
Stem length Tall (L) Dwarf (l)
Seed shape Round (R) Wrinkled (r)
If a plant that is heterozygous for all three traits were allowedto self-fertilize, what proportion
of the offspring would be expected to be as follows?
a. Homozygous for the three dominant traits
b. Homozygous for the three recessive traits
c. Heterozygous for the three traits
d. Homozygous for axial and tall, heterozygous for round.
