What do geneticists call alleles that are both expressed in the phenotype when they are together?
a.) hybrids
b.) codominance
c.) heterozygous
d.) incomplete dominance

I think the correct answer from the choices listed above is option B. Alleles  that are both expressed in the phenotype when they are together are called codominance. Alleles are masked or hidden by dominant alleles. Hope this answers the question. Have a nice day.
