Hey Hii...
Here is your answer...
Characters are determined by two or more gene pairs,and they have additive or cumulative effect.Such genes are called cumulative genes or polygenes or multiple factor.
It was concluded that the kernel colour is under control of two pairs of alleles.The two pairs of alleles segregate independently of each other as in Mendel's dihybrid crosses.The two genes contribute in the production of pigment and a graded phenotype is produced.
