Gregor mendel crossed true-breeding plants with green pea pods with true-breeding plants with yellow pea pods. the resulting f1 generation all had green pea pods. what did he observe in the f2 generation?

a. mendel observed green and yellow pea pods in a 3: 1 ratio because the f1 generation was heterozygous.
b. mendel observed green and yellow pea pods in a 4: 1 ratio because the allele for green pea pods is dominant.
c. mendel observed green and yellow pea pods in a 1: 1 ratio because the f2 generation had the same characteristics as the parent generation.
d. mendel observed only green pea pods because both parents had green pea pods.
e. mendel observed green and yellow pea pods in a 1: 2 ratio because the allele for yellow pea pods is dominant.
