    Flashcards

    F1 generation

    The offspring produced from the cross between the parental generation (P) in a monohybrid cross.

    Codominance

    Both alleles are fully expressed in a heterozygous individual, resulting in a phenotype that displays characteristics of both alleles.

    Blood type AB

    Blood type AB results from the presence of both IA and IB alleles, where both are fully expressed.

    Heterozygous

    An individual with two different alleles for a specific trait.
