Sex Linked DisordersCurrent LectureDefinitionsI. Incomplete Dominance: when phenotype of heterozygous is intermediate between the phenotypes of individuals homozygous for either allele.II. Monohybrid: Cross between two organisms that are heterozygous for the character being followedIII. Dihybrid: Cross between two organisms that are each heterozygous for both of the characters being followed.IV. Codominance: the situation where the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate, distinguishable ways.Blood Type:Types: I. Aa. Genotype: AA, AOII. Ba. Genotype: BB, BOIII. ABa. Genotype: ABIV. Oa. Genotype: OOThese notes represent a detailed interpretation of the professor’s lecture.
