1. You cross two pea plants to create F1 progeny that are heterozygous for all 5 traits.
a. What is the probability of one F1 plant generating a gamete with alleles for green peas that are wrinkled OR smooth?
b. If you now cross two F1 plants, what proportion of offspring would have smooth, yellow peas with constricted pods, terminal flowers, and dwarf stems?
c. From this same cross, what proportion of offspring would have smooth, green peas with inflated pods, axial flowers and dwarf stems?
