Almond-shaped (E) eyes is dominant over round eyes. Presence of freckles (F) is also a dominant trait. Medium-sized nose, however, may be inherited if one parent has a large (L) nose and the other has a small (S) nose. Achondroplasia (A) is an autosomal dominant disorder that leads to dwarfism but not lethal. A woman homozygous for normal height, with freckles, almond-shaped eyes, small nose, and Type A blood, has a Type O mother with no freckles and a type AB father with round eyes. She is engaged to a man with achondroplasia, round eyes and medium sized nose. Unlike his father, his mother is of normal height. Both his parents have Type O blood but nobody from both sides of his family has or had freckles. 1.What is the complete genotypes of the man and the woman. Clearly indicate which genotype belongs to whom? 2.Based on their genotypes, what is the probability that they will have: - a child with Achondroplasia? - a child of normal height? - a child with type AB blood?
