In a species with incomplete dominance, the genotypic and phenotypic ratios will be
a. the inverse of each other (3: 1, 1: 3)
b. identical (1: 2: 1, 1: 2: 1)
c. different (3: 1, 1: 2: 1)
d. unable to be compared.

correct option is b identical (1:2:1,1:2:1)

Explanation:

In order to assess the most likely results of the crosses for those genes that display incomplete dominance, Mendel's model can be is used because these genes are acquired in retained  with Mendel's fundamental rules, even if they all exhibit incomplete dominance. This can be clarified by adopting an instance of green crop inter-fertilization producing a feasible 1:2:1 genotype ratio and 1:2:1 phenotype ratio.

so correct option is b identical (1:2:1,1:2:1)
