Is Roan Dominant

Genetics. Roan is a simple dominant trait symbolized by the Rn allele. Traits that are dominantly inherited cannot skip generations, meaning that two nonroan parents cannot produce a roan offspring. In cases where roan has appeared to skip generations, one of the parents is usually discovered to be slightly roaned.

What is the genotype for roan?

Genotypes of Roan Coats Although roan generally refers to cattle and horses with both red and white hairs, other roan colors also occur. The roan cow genotype for the blue cow happens when a purebred black cow (genotype CBCB) breeds with a purebred white cow (genotype CWCW), resulting in the genotype CBCW offspring.
