9. We will determine if the pedigree below can be for a trait that is autosomal dominant. Use "A" and "a" where A represents the dominant allele and "a" is the recessive allele. Darken symbol means the individual exhibits the dominant trait.e a) Write the genotype of each individual next to the symbol.e b) Is it possible that this pedigree is for an autosomal dominant trait?e

3) The most likely inheritance pattern in the pedigree above is:
Two autosomal mutations include albinism and dwarfism. Albinism (a) is recessive, and dwarfism (D) is dominant. Complete a dihybrid cross of two people that are heterozygous for normal pigmented skin. One person is normal height and has no genetic trace of dwarfism in the family. The other person has dwarfism but has a mother who is normal height. 21. Complete a full dihybrid Punnett square (6pts).
