- A young couple went to see a genetic counselor because each had a sibling with cystic fibrosis. (Cysticfibrosis is a recessive disease, and neither member ofthe couple nor any of their four parents is affected.)a. What is the probability that the female of thiscouple is a carrier?b. What are the chances that their child will havecystic fibrosis?c. What is the probability that their child will be acarrier of the cystic fibrosis disease allele?The pedigree below represents the inheritance of a rare genetic disorder (members joining the pedigree are not carriers). Consider the following pedigree and answer questions (i) to (vii) below. The allele descriptors are B/b. What is the mode of inheritance in this pedigree ? Y-linked inheritance X-linked recessive inheritance X-linked dominant inheritance Autosomal recessive inheritance Autosomal dominant inheritance What is the genotype of individual III-2 ? a) XbXb b) XBXB c) XBXb d) Bb e) bb What is the genotype of individual IV-3 ? a) XbXb b) XBXB c) XBXb d) Bb e) bb Individual IV-4 and an unaffected woman is planning a family. What is the probability that their first child will be phenotypically normal ? a) chance that the first child will be phenotypically normal. b) chance that the first child will be phenotypically normal. c) chance that the first female child will be phenotypically normal; all male children will be phenotypically normal. d) chance that the…Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___
