Autosomal dominant disorders achrondroplastic dwarfism polydactyly (6 fingers and 6 toes) autosomal co-dominant disorders. A and b blood types familial hypercholesterolemia (elevated cholesterol levels in blood) Abo blood types multiple allele traits polygenic inherited traits height weight skin color x-linked recessive traits color blindness hemophilia muscular dystrophy (rapid deterioration of the muscles by age 6-7 years followed by death) True or false: according to the blending theory of inheritance each species has a fixed and unchanging set of characteristics. false. A pea with yellow seeds is crossed with one that makes green seeds. When these f1 progeny were crossed with each other 75% of the f2 progeny had yellow seeds and 25% had green seeds. If a pure-bred tall pea plant is crossed with a pure-bred dwarf plant what fraction of the progeny will be dwarf? zero (all tall but heterozygous)
