Step by step
Solved in 2 steps
- Why is autosomal Monosomy lethal?Two affected daughters and two normal sons are born to an affected male and a normal female. Each of the affected daughters (and their normal husbands) gave birth to affected sons and daughters. Normal sons of the couple married normal women and had normal children. Which of the following is the most likely mode of inheritance for this trait?* Sex-linked recessive Sex-linked dominant Autosomal dominant Autosomal recessiveNeurofibromatosis-1 (NF1) is an autosomal dominant disorder where tumours form in the base layer of the skin or in nerve tissues. What is the probability that individuals II-1 and II-2 will have a genetic son with NF1? Find the image attached.
- Does the phenotype indicated by the red circles and squares in this pedigree show an inheritance pattern that is autosomal dominant, autosomal recessive, or X-linked?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?A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
- Why the allele for Huntington disease is dominant?A WOMAN IS HETEROZYGOUS FOR TWO HARMFUL RECESSIVE ALLELES IN DIFFERENT CHROMOSOMES, ONE FOR PHENYLKETONURIA (PKU) AND THE OTHER FOR CYSTIC FIBROSIS (CF). SHE MARRIES AN UNAFFECTED MAN WHO IS A CARRIER FOR NEITHER DISEASE. IF SHE HAS A DAUGHTER, WHAT IS THE PROBABILITY THAT THE CHILD WILL CARRY NEITHER OF THE RECESSIVE ALLELES? EXACTLY ONE? BOTH?Hypophosphatemia 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.
- Huntington's disease is a late-onset autosomal dominant disorder. What is the chance that a heterozygous woman with the disease will pass the affected allele on to her children? 0% 75% 100% 25% 50%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?________________Genes involved in sex-limited inheritance are found in autosomal genes? True or false
