11. The probability of two carriers having a child with cystic fibrosis is 0.25. If a...
An individual heterozygous for cystic fibrosis a) Will have children who are all carriers of cystic fibrosis. b) Cannot have children with cystic fibrosis. c) has cystic fibrosis d) is a carrier
Consider a family with three children in which both parents are carriers for cystic fibrosis. What is the probability that they will have no affected children? 1) 0 2) 1/64 3) 9/64 4) 16/64 = 1/4 5) 27/64
1. Joe and his wife Mary do not have Cystic fibrosis, but are both carriers of the disease. (a) If the couple had three children what are the odds that two will have cystic fibrosis and one will be normal? (b) What are the odds the couple will have four children and all of them will not have cystic fibrosis? (c) What are the odds if they had two children that both of the kids would have the same phenotype...
Parents who do not have cystic fibrosis (recessive) produce a child who has cystic fibrosis. What are the chances that each child born to this couple will have cystic fibrosis? 100% 75% 25% 0% All of the choices are correct. Could a man with blood type A father a child with blood type B? No, only males with type B or AB can have children with type B blood. Yes, if his genotype was AO and the mother had type...
Use the following info to answer questions 12-13: Cystic Fibrosis is a disorder passed on genetically. Since Sue and Sam are both carriers of this disorder, it means that each of their children has a 25% probability of contracting the disease. 12. Complete both parts showing all work by hand - no statsrunch A) Sue and Sam have 5 children. Find the probability exactly one of their children has Cystic Fibrosis. (Round to at least two decimal places.) B) Sue...
1 A) Cross Rh- man who is heterozygous for cystic fibrosis with a female who is heterozygous for cystic fibrosis and Rh+. What are the phenotypes and phenotypic ratios of the offspring? B) Cross a Rh- man who is left handed with a female who is heterozygous Rh+ and right handed. What are the expected phenotypes? C) The parents of two children are normal in respect to cystic fibrosis. One of their children is normal, one has cystic fibrosis. What...
A human disease known as cystic fibrosis is inherited as a recessive trait. For example, the possible outcomes of a child inheriting cystic fibrosis genes are CC Cc cC cc if the child’s parents had one copy of each version of the gene so the probability of having a disease is ¼. Find the probability that 3 out of 6 children of these parents will have a cystic fibrosis.
Approximately 1 in 120 Asian Americans are carriers of cystic fibrosis. What is the approximate relative risk of this female having a child affected by cystic fibrosis with a Northern European partner, compared to an Asian American partner, assuming that both are of unknown genotype? 4.5-fold 2.2-fold 1.8-fold 0.2-fold
5) Human recessive disease: cystic fibrosis Jane and John are expecting a baby know that they are both carriers (i.e., heterozygous) of cystic fibrosis (Cc). What is the probability that their child will have cystic fibrosis (CC)? What is the probability that their child will be a carrier of cystic fibrosis? Chance of child being: 25 % Homozygous dominant Genotype: 50_%Cystic fibrosis carrier Genotype: 25 % Cystic fibrosis Genotype: 6) Human recessive disease: Phenylketonuria A couple has just found out...
Cystic fibrosis is a lung disorder that often results in death. It is inherited but can be inherited only if both parents are carriers of an abnormal gene. In 1989, the CF gene that is abnormal in carriers of cystic fibrosis was identified. The probability that a randomly chosen person of European ancestry carries an abnormal CF gene is 1/25. (The probability is less in other ethnic groups.) The CF20m test detects most but not all mutations of the CF...
