Among the following, choose the traits of pea as identified by Mendel, whose genotypes may be either homozygous or heterozygous.
A. Yellow pods
B. Yellow seeds
C. Green pods
D. Green seeds
Only the dominant traits of pea can have the genotypes either in homozygous or heterozygous condition. Recessive traits always have homozygous genotypes. In pea, yellow seeds and green pods are dominant traits. Hence, their genotypes may be either homozygous or heterozygous.
