Incomplete Dominant Aa genotype have a phentoype that is intermediate between AA and aa. Codominant Aa genotype has both the AA and aa phenotypes. Chapt er 10, page 5 Penetrance is when some percentage of a given genotype fails to express the expected phenotype Expressivity is when a given genotype gives a range of phenotypes Chapt er 10, page 6 Chapt er 10, page 7 Chapt er 10, page 8 Chapt er 10, page 9 Chapt er 10, page 10 Chapt er 10 Key Words: Allele Dominance, Recessive Codominance Dihybrid cross, Monohybrid cross Expressivity Gene P, F1, F2 Genotype, Phenotype Incomplete dominance Locus Mutation Penetrance Pleiotropy Polymorphism Trait Wild type Autosome Hemizygous Heterozygous Homozygous Independent assortment Reciprocal crosses Recombinant Segregation Sex chromosome Sex linkage Test cross Chapt er 10, page 11 Chapt er 10 Highlights: I.
