- An allele responsible for Marfan syndrome Section 13.4 is inherited in an autosomal dominant pattern. What is the chance that a child will inherit the allele if one parent does not carry it and the other is heterozygous?Hemophilia is an X-linked recessive disorder and blood type is autosomal. If two healthy parents, one of which is blood type A and the other blood type B, produce a son who has hemophilia and is type O, what is the probability that their next child will be a son with hemophilia and blood type B? 1/2 3/16 1/4 1/8 1/16A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a phenotypically normal man with no family history of hemophilia.

- Huntington's disease is caused by a autosomal dominant that is lethal in embryos in the homozygous dominant conditionIf one of your parents has the disease and the other does notwhat is the probability that you will develop the disease? assume if you inherit the Huntington's gene you will get the disease)? 1/4 0 1/2 3/4A woman with Huntington’s disease (autosomal dominant trait, and she is heterozygous) has children with a healthy man. What proportion of their children will inherit Huntington’s disease?Huntington’s disease, a neurodegenerative genetic disorder that typically becomes noticeable in middle age, is due to an autosomal dominant allele. Sickle cell anemia, on the other hand, is a genetic blood disorder due to a recessive allele. Mary is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Paul whose father died of Huntington’s disease. His mother, however, is not inflicted with that condition. Neither of his parents exhibits sickle cell anemia. What are the genotypes of Jane and Paul? If they plan to have four children, what is the probability that: all their children will be normal? _________________________________ they will have a son with Huntington’s disease? _________________________ they will have a daughter inflicted with both conditions?________________

- Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh. What is the percent probability that the first child of this couple will have Huntington's disease? probability: % What is the percent probability that two of the seven children will have Huntington's disease? probability: %A WOMAN IS HETEROZYGOUS FOR TWO HARMFUL RECESSIVE ALLELES IN DIFFERENT CHROMOSOMES, ONE FOR PHENYLKETONURIA (PKU) AND THE OTHER FOR CYSTIC FIBROSIS (CF).
