Explain how a single allele can exhibit both complete dominance and codominance?
zubka84 [21]

Complete dominance is only one allele in the genotype seen in phenotype .Both alleles genotype are seen in the phenotype.

Alleles aren't fully dominant or recessive to one another, but instead display co-dominance and dominance. Co-dominance occurs when Allen show dominance. ABO blood group is good example of multiple alleles which shows co-dominance passed from parents to the offspring.

Dominance in which dominant allele is fully expressed while suppressing recessive allele effect on phenotype.and co-dominance  are the process in which both alleles independently work and express effect without mixing the effects.Both are two types of genetic inheritance. It is a condition which has dominant allele does not completely mask the effect of recessive allele.
