Answer:
The correct answer will be option-B
Step-by-step explanation:
Dominance is the phenomenon observed in the genes coding for a trait in which the one variant of a gene called allele masks the effect of a complementary allele at same locus coding for the same trait.
The concept of dominance was observed by Gregor Mendel during his experiments on Pea related to study the inheritance pattern.
Since in dominance, one allele masks the effect of complementary allele therefore the dominant allele shows its effect and different genotypes produce the same phenotype.
Thus, Option-B is the correct answer
