Question

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

Explanation:

Codominance is a genetic phenomenon where both alleles in a heterozygote are fully expressed. In the case of black and brown spotted coat color in horses, both the black and brown alleles are expressed simultaneously, showing distinct spots. Tall and short plant heights and seed shape in pea plants are examples of simple Mendelian dominance (one allele masks the other). Black and yellow coat color in Labrador retrievers is due to a different genetic mechanism (not codominance as the two colors are not expressed simultaneously in a codominant way like spots).

Answer:

black and brown spotted coat color in horses
