7. Take a look at the following families and decide if the trait is autosomal dominant, autosomal recessive or X-linked recessive?

8. Construct a Punnett square for a cross between a heterozygous black guinea pig and a homozygous white guinea pig. a. What genotypes would you expect in the offspring? b. What percentage or ratio of each genotype would you expect in the offspring? C. What phenotypes would you expect in the offspring?

5. Sickle cell disease is inherited in an autosomal recessive manner. If Josh and Katie each have a sibling with sickle cell disease, but neither Josh nor Katie nor any of their parents have the disease, then what is the chance that a child of Josh and Katie's will have sickle cell disease? (Hint: First determine the chance that Josh and Katie are carriers of the disease.)

2. My mom is colorblind, which is an X-linked recessive disorder. My dad has normal color vision. I have normal color vision, as does my husband. What are the chances that my son, Liam, and my daughter, Sloane, are colorblind? There are two Punnett square provided below, one for each generation.

5. A husband and wife have typical vision, although both of their fathers are red-green colorblind (an X-linked recessive trait). From this information, determine the appropriate symbols for the wild-type and color-blind alleles and write the genotypes of the husband and wife. a. b. What is the probability that the couple will have a son with typical vision? C. What is the probability that the couple will have a daughter with typical vision? d. What is the probability that the couple will have a son with colorblindness? e. What is the probabilityt the the couple will have a daughter with colorblindness?

5. The pedigree below traces the inheritance of Albinism, a genetic disorder. Affected individuals, indicated here by the coloured circles and squares, are unable to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair colour. Does Albinism appear to be caused by a dominant allele or by a recessive allele? Fill in the genotypes of the individuals whose genotypes can be deduced. What genotypes are possible for each of the other individuals? Explain! Naruto Hinata Reiner Asta Hange Mikasa Eren Historia Luffy Nezuko Zenitsu Tanjiro Son Goku

7. Hereditary ichthyosis in humans is a sex-linked trait. If a normal male and a carrier female produce offspring, what will be the phenotypic ratios of: Normal females to scaly females? Normal males to scaly males? 8. Raedwald is color blind. His four sisters and his parents all have normal color vision. Who passed this condition on to Raedwald, and what can be said for certain about the genotypes of his maternal and paternal grandparents? wwwwM

4. In the pedigree shown, the trait is most likely caused by what type of inheritance?   X-linked dominant   autosomal recessive   autosomal dominant   X-linked recessive

5. Cystic fibrosis in humans is caused by a recessive allele. Two unaffected parents have a child with cystic fibrosis. a. What is the probability that this couple's next child will be unaffected?
