co dominance inheritance e.g coat colour in cattle

• • Both alleles are independently and equally expressed within heterozygous creating a new phenotype
  • One allele is not dominant over the other and there is no recessive allele
• • Phenotypes are red, white or roan colour
  • Genotypes
  • Red– C^R C^R
  • White – C^W C^W
  • Roan– C^R C^W
  • Roan coat colour in cattle
• Both red and white alleles expressed and both red and white hair colours seen throughout the coat
