Question

Which is an example of codominance?
A. Black and brown spotted coat color in horses
B. Seed shape in pea plants
C. Black and yellow coat color in Labrador retrievers
D. Tall and short plant heights

Answer 1

An example of codominance is:

**A. Black and brown spotted coat color in horses.**

In codominance, both alleles in a heterozygous organism contribute to the phenotype, resulting in a phenotype that shows both traits simultaneously, as seen in the spotted coat of horses. The other options represent different types of inheritance: B (seed shape) refers to complete dominance, C (Labrador coat color) has a different inheritance pattern, and D (plant heights) also shows complete dominance.
