(C) In Mendelian inheritance (complete dominance), the $F_2$ phenotypic ratio is $3:1$ and the genotypic ratio is $1:2:1$.In incomplete dominance, the dominant allele does not completely mask the recessive allele, resulting in an intermediate phenotype. For example, in $Mirabilis jalapa$, the cross between red $(RR)$ and white $(rr)$ flowers produces pink $(Rr)$ $F_1$ offspring. Selfing $F_1$ $(Rr 	imes Rr)$ results in an $F_2$ ratio of $1$ Red $(RR)$ : $2$ Pink $(Rr)$ : $1$ White $(rr)$. Thus, both genotypic and phenotypic ratios are $1:2:1$.In co-dominance, both alleles are expressed equally in the heterozygote. For example, in $ABO$ blood grouping or coat color in cattle, the $F_2$ ratio is also $1:2:1$ for both genotype and phenotype.Therefore, both incomplete dominance and co-dominance exhibit the same genotypic and phenotypic ratios in the $F_2$ generation.

In $F_2-$generation, genotypic and phenotypic ratios are the same in the case of $-$
