Answer #1

Option b. Incomplete dominance is a condition where neither of the allele suppresses the effect of the other allele, when present together (heterozygote). The phenotypes of both dominant and recessive allele mix to form a new phenotype. The new phenotype is an intermediate between the phenotype of the homozygotes. For example, when cattle having red coat (RR) is crossed with cattle having white coat (rr), the coat color of the offspring is roan (Rr), which is a blend of the two homozygotes.
