(B) In codominance,both alleles of a gene pair express themselves equally in the $F_1$ hybrid. In short-horned cattle,the allele for red coat colour $(R)$ and the allele for white coat colour $(r)$ are both expressed in the heterozygote $(Rr)$,resulting in a roan phenotype (a mixture of red and white hairs). Therefore,this is a classic example of codominance.

Medium

In short-horned cattle,genes for red $(R)$ and white $(r)$ coat colour occur. $A$ cross between red $(RR)$ and white $(rr)$ produces $(Rr)$ roan. This is an example of:
