What color offspring result from co-dominance?

• A. Uniform color
• B. A blend color
• C. A random color in each offspring
• D. Erminette color offspring

Answer: (D)

In co-dominance, both alleles are expressed in the phenotype. A classic example is roan or Erminette coat color, where red and white alleles are both active in heterozygotes, producing a coat with red and white hairs intermingled rather than a single uniform shade. This isn’t a blended intermediate color, and it isn’t random from one offspring to the next; it’s a direct expression of both colors in the heterozygous genotype. So the color that results in this pattern is Erminette.
