Codominance

The video explains codominance, where both alleles are expressed in the phenotype, unlike monohybrid crosses where one allele is dominant. Examples include speckled chickens and blood groups. Blood group genetics are detailed, showing how IA and IB are codominant, while IO is recessive. A Punnett square is used to illustrate possible offspring genotypes from parental alleles.

How do blood groups relate to codominance? Explain the inheritance pattern.
