In a parental cross of a ADHL disease trait, where the father is affected and the mother is unaffected, 50% of the offspring will have the disease phenotype and 50% will have the WT phenotype. In an F1 cross between an affected male and an unaffected female, the expected proportions of the Disease Phenotype and the WT phenotype, respectively, are: a. 0.667 and 0.333. b. 0.50 and 0.50. c. 0.333 and 0.667. d. 0.0 and 1.0 e. 0.75 and 0.25.
