Genes of pea that influence incomplete dominance pattern of inheritance with respect to size of starch grains also influence dominance pattern of inheritance with respect to the following character.

 Genes of pea that influence the incomplete dominance pattern of inheritance has its alleles as B and b. If the genotype is BB, the starch grains formed are larger. If the genotype is Bb, the starch grains have intermediate or medium size and in case of bb, the starch grains are smaller. For genotypes BB and Bb, the seeds are round and for bb the seeds are wrinkled.
