Clarence made a diagram to compare codominance and incomplete dominance. which label belongs in the area marked y? neither allele is dominant. an intermediate phenotype is expressed in offspring. one allele is dominant over the other. both dominant alleles are fully expressed in offspring.

The correct answer is both dominant alleles are fully expressed in offspring.      

In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.  

In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.

Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.      

The answer is both dominant alleles are fully expressed in offspring.
