Mendel also worked with two characters on pea plant. He chose color and shape of the seed to explain the inheritance of two genes.
Y – dominant yellow color
y – recessive green color
R – round shape of the seed
r – wrinkled shape of the seed
Phenotypic Ratio:
Round yellow : round green : wrinkled yellow : wrinkled green
9 : 3 : 3 : 1
