Affected individuals are shown with filled (black)symbols.arrow_forwardIn the human pedigree shown below, black filled symbols indicate individuals suffering from a rare genetic disease, whereas empty symbols represent people who do not have the disease.

- Ann's family has a history of cystic fibrosis, a recessive genetic disease. In the pedigree, family members who are afflicted with the disease are shown in red. Members who are unafflicted may or may not be carriers.

- What is the most likely pattern of inheritance for this disorder? (Is it autosomal dominant? Autosomal recessive? X-linked dominant? X-linked recessive? Y-linked? Mitochondrial?) Please include two specific pieces of evidence, present within the pedigree, that indicate that this pattern is most likely, as opposed to any other potential pattern. You may assume that the gene responsible for the trait is fully penetrant.arrow_forwardHypophosphatemia is a dominant genetic disorder caused by a deficiency of phosphates in the blood. Assuming the other parent is free of the disorder, males with the disorder will pass it on to all their daughters, but not their sons. Females with the disorder will pass it on to approximately half of their children. Is this pattern of inheritance autosomal or sex-linked? Draw Punnett squares to show the inheritance pattern of the disorder in each of the two scenarios.arrow_forwardFor each of the listed modes of single gene inheritance (assuming complete penetrance), indicate whether it is POSSIBLE or IMPOSSIBLE, given this pedigree. nс Autosomal recessive 11 [Select] Autosomal dominant [Select] Autosomal recessive, sex-limited to males [Select] Autosomal dominant, sex-limited to males [Select] 13 Autosomal recessive, sex-limited to females [Select] Autosomal dominant, sex-limited to females [Select] Autosomal, sex-influenced, dominant in males [Select] Autosomal, sex-influenced, dominant in females [Select] X-linked recessive [Select] Y-linked [Select] X-linked dominant [Select] X-linked recessive, sex-limited to females [Select] X-linked dominant, sex-limited to females [Select] X-linked, sex-limited to males [Select] X-linked, sex-influenced, dominant in females [Select] X-linked, sex-influenced, recessive in females [Select]arrow_forward
