Which type of dominance occurs when the phenotype of the heterozygote is intermediate between the phenotypes of the homozygotes?

• Complete dominance

• Incomplete dominance

• Codominance

• Overdominance

In codominance, how are the alleles expressed in the phenotype?

• Only the dominant allele is expressed

• Only the recessive allele is expressed

• Both alleles are fully expressed

• Neither allele is expressed
