In case of starch synthesis in pea seeds [controlled by B gene], BB homozygotes produce large and round starch grains; bb homozygotes produce smaller and wrinkled starch grains and Heterozygotes produce round seeds of intermediate size. What can be inferred from this observation?
(1) The gene B mutates at a faster rate.
(2) The gene B is easily influenced by the environment
(3) Dominance is not an autonomous feature of a gene or the product that it has information for
(4) Some genes do not follow the law of segregation.
