Flower position, stem length, and seed shape were three characters that Mendel studied. Each is controlled by an independently assorting gene and has dominant and recessive expression as follows:
Character Dominant Recessive
Flower Position Axial (A) Terminal (a)
Stem Length Tall (T) Dwarf (t)
Seed Shape Round (R) Wrinkled (r)
If a plant that is heterozygous for all three characteristics is allowed to self-fertilize, what proportion of the offspring would you expect to be as follows?
a. homozygous for the three dominant traits
b. homozygous for the three recessive traits
c. heterozygous for all three characters
d. homozygous for axial and tall, heterozygous for seed shape
