Question

completely dominant over the other. this is expressed when two dominant alleles cross - pollinate and create a blend.
codominance
codominance is where two dominant alleles are exhibited, and they dont blend with each other. the result is that the traits produced by both alleles are expressed at the same time.
multiple alleles
multiple alleles are very common because a lot of genes have more than two alleles for a particular trait so there are more possible alleles existing in a population.
what do we call the process when two dominant alleles are expressed and do not create a blend?
minor dominance
codominance
multiple alleles

Explanation:

The question asks for the process where two dominant alleles are expressed without blending. The codominance section explicitly states that in codominance, two dominant alleles are exhibited and don't blend, with traits from both alleles expressed simultaneously. Minor dominance isn't a standard genetic term in this context. Multiple alleles refer to more than two alleles for a trait in a population, not the non - blending of two dominant alleles.

Answer:

B. codominance
