A. Analyze the pedigree below and determine if the trait is inherited as autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, or Y-linked. Remember, data from human families is limited, so you may be unable to determine the inheritance with certainty. The key is that you justify your answer using data from the pedigree. 2 4 0-4

. The following pedigree is for a dominant phenotype governed by an autosomal allele. What does this pedigreesuggest about the phenotype, and what can you deduceabout the genotype of individual A?

One family is shown in both pedigrees below. Each pedigree focuses on a different monogenic, fully penetrant phenotype. Shaded individuals affected by Phenotype 1: 3 Shaded individuals affected by Phenotype 2: a. Phenotype 1: Which modes of inheritance can be ruled out, base don't this pedigree? For each mode of inheritance listed below, either state that it is not ruled out, or describe a detail of the pedigree that allows you to rule it out. Autosomal recessive Autosomal dominant X-linked recessive X-linked dominant Y-linked b. Phenotype 2: Which modes of inheritance can be ruled out, base don't this pedigree? For each mode of inheritance listed below, either state that it is not ruled out, or describe a detail of the pedigree that allows you to rule it out. Autosomal recessive Autosomal dominant X-linked recessive X-linked dominant

Assumptions: . If the parent expresses the trait, they are homozygous dominant If the child/children express the trait but the parents do not, the parents are heterozygous. Traits selected: Brown Hair/Eyes And Widows Peak Write the Letters you will be using n the Punnet square for each trait: _Ww Bb_and_ww Bb_ Father Genotype: WW Bb Mother Genotype: ww Bb Parent Gametes possible gametes: possible gametes: Do you have the phenotype of either of the traits in the cross? If you do, which one? Are there any other offspring with either trait? Which trait? Which phenotypic probability did you fall into? Which phenotypic probability did other offspring fall into? I
