a. Determine if the pedigree below can be for a trait that is X-linked traits. Write the genotype of each individual next to the symbol. b. Is it possible that this pedigree is for an X-linked recessive trait? c. What can you conclude about the children if both parents are affected with an X-linked recessive trait?

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

Examine the pedigree and answer the following questions; shaded individuals show the trait; genotypes are all unknown. The individual marked with the question mark is of an unknown genotype but does have the trait. A. What mode of inheritance is the most likely for this trait, autosomal recessive or autosomal dominant? State your rationale for full credit. B. What is the genotype of the individual marked with the question mark? (Heterozygous, homozygous, or unknown)

Blood types in humans are Codominant. a. What are the possible genotypes of someone with type O blood? b. What are the possible genotypes of someone with type B blood? c. What is the phenotype of someone’s whose genotype is AO? d. A man with AB blood is married to a woman with AB blood. What blood types will their children be and in what proportion?

Is the inheritance pattern indicated by the shaded symbols in this pedigree consistent with the inheritance pattern of an X-linked recessive characteristic? Select one: a. Yes b. No

Examine the pedigree and answer the following questions; shaded individuals show the trait; genotypes are all unknown. The individual marked with the question mark is of an unknown genotype but lacks the trait. A. What mode of inheritance is the most likely, autosomal recessive or autosomal dominant? State your rationale for full credit. B. What is the genotype of the individual designated with the question mark? (Heterozygous, homozygous, or unknown). C. What are the genotypes of the parents in generation I? (Heterozygous, homozygous, or unknown). D. What are the genotypes of the three children of generation IV? (Heterozygous, homozygous, or unknown).
