In Pea, the gene for starch synthesis influences the following phenotypes in the plant
A. color of the seed B. shape of seed
C. size of starch grains D. stem height
Gene for starch synthesis in Pea is a pleotropic gene. It influences the shape of seed and size of starch grains. The gene is represented with the letter “B” as dominant one and ‘b’ as recessive one. Plant with genotype as BB has Round seeds and produces larger starch grains. Those having genotype as Bb form round seeds but size of starch grains is medium. Plants with bb as genotype form wrinkled seeds and smaller starch grains. In terms of shape of the seed it shows dominance pattern of inheritance and in terms of size of starch grains it shows incomplete dominance pattern of inheritance.
