Explanation

In starch synthesis gene following condition to seen BB – rounded (due to more starch synthesis) bb – wrinkled (due to less starch synthesis) Bb – in between rounded of wrinkled size. It produce starch of intermediate quantity between BB to bb homozygous condition. So, it is incomplete dominance. Therefore, dominance is not an autonomous feature of a gene or the product that it has information for. It depends as much on the gene product and the production of a particular phenotype from this product as it does on the particular phenotype that we choose to examine, in case more than one phenotype is influenced by the same gene
