which is an example of codominance? (1 point)
black and brown spotted coat color in horses
seed shape in pea plants
tall and short plant heights
black and yellow coat color in labrador retrievers
item 1
item 2
item 3
item 4
item 5

Explanation:

Codominance occurs when both alleles for a trait are fully expressed in the phenotype, resulting in a combined, distinct trait rather than a blended one.

• Seed shape in pea plants and tall/short plant heights are examples of complete dominance, where one allele masks the other.
• Black and yellow coat color in Labradors is an example of recessive epistasis, not codominance.
• Black and brown spotted coat color in horses shows both alleles being fully expressed simultaneously, which fits the definition of codominance.

Answer:

black and brown spotted coat color in horses
