What is the inheritance pattern observed in the size of starch grains and seed shape of Pisum sativum?

What is the inheritance pattern observed in the size of starch grains and seed shape of Pisum sativum?
Workout the monohybrid cross showing the above traits.How does this pattern of inheritance deviate from that of Mendelian law of dominance?

A Single gene controls the size of the starch grain and the seed shape.
The train of size of starch grain shows incomplete dominance.Hence in heterozygous condition the starch grain are of intermediate size.
