tion 8: below is the pedigree of inheritance of phenylketonuria (PKU). We will designate the letter Caven for the dominant allele and "p" for the recessive allele. 4 The pedigree shows that the pattern of inheritance for the allele for phenylk ylketonuria is: I. II. 1 III. IV. Autosomal dominant Autosomal recessive X-linked dominant X-linked recessive b. The parents in generation I have how many children: I. 3 Boys II. 3 Girls III.

Name Sofia Falcione P Pedigree Analysis Practice - for each pedigree, write the genotypes of the individuals The disorder shown on the pedigree is Maple Syrup Urine Disease (MSUD) which is a metabolic disorder that affects the body's ability to process certain proteins. It was named after a distinctive odor of a baby's urine. 1. What is the inheritance pattern of this gene? a) autosomal dominant b) autosomal recessive c) X-linked recessive 2. Provide at least one piece of evidence for your claim. This pedigree shows the inheritance Leber congenital amaurosis (LCA) which is a type of hereditary blindness. Individuals with this disease lose their vision during childhood. 3. What is the inheritance pattern shown? 4. Highlight one individual whose genotype is unknown. What additional information would you need to determine his/her genotype? Marfan syndrome affects the connective tissue and causes individuals to have long, thin, arms, legs, fingers and toes. 5. What is the inheritance…
40 Below is a pedigree of a family, some of whom have the autosomal dominant condition Huntington's disease. Affected individuals are indicated by a dark square or circle. The male in generation I (indicated by the arrow) is heterozygous for the Huntington's disease mutation. The following two questions relate to this pedigree. Generation II II If H represents the disease allele, and h the wild type allele, what is the genotype of the individual indicated by the *? Select one alternative: O hh O Hh O hH O HH
Use keyboard only to enter your answer below. ALL WORKING MUST BE SHOWN Problem 1) mutation in a gene on chromosome 15 that codes for an enzyme. The disease is an inherited autosomal recessive condition which is Tay-Sachs disease is caused by loss of function found amongst Ashkenazi Jews of Central European origin. In this population, 3 in 5,200 children are born with the disease. What proportion of the population are carriers (heterozygotes) for this disease?
Problem 3: Consider the accompanying pedigree of a rare 11 ||| IV A B omal recessive disease, PKU. a. List genotypes of as many of the family members as possible. b. If individuals A and B marry, what is the probability that their first child will have PKU? c. If their first child is normal, what is the probability that their second child will have PKU? d. If their first child has the disease, what is the probability that their second child will be unaffected?
Question:- Based on your selected mode of inheritance, show the genotypes for the following individuals. [Use these symbols for alleles: if it is autosomal, then use the symbols B - dominant, b - recessive (e.g. BB, bb etc.) if it is X-Linked, then X(B) - dominant, X(b) - recessive, and Y for Y-chromosome (e.g. X(B)X(B), X(B)Y etc.) ] I-1 I-2 II-7 II-8 III-10 III-11 III-12 IV-8 IV-9
PEDIGREES: Problem 7 (continued) This pedigree shows the inheritance of a type of X-linked color blindness. It is a recessive trait. Carriers have NOT been half-shaded in this pedigree. QUESTIONS ••• I O 10 3. Use the letter "b" to represent the color blindness allele. What is the 1 3 4 genotype of individual IV-1? II 4.

1 (b). Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,o00 tested. Assuming Hardy-Weinberg conditions, What is the percentage of heterozygous carriers? (Give your answer in whole number, no decimal places, and include the % symbol without a space).
The next four questions are all related to this problem: Polydactyly (PD) is an autosomal dominant trait (polydactyly - P; wildtype - p). Cystic fibrosis (CF) is an autosomal recessive trait (cystic fibrosis - f; wildtype - F). A PD woman, otherwise normal in phenotype, marries a healthy normal man. Their 4 children are: 1) normal, 2) PD, 3) CF, 4) CF + PD. You will walk through a series of steps to answer this question: What is the probability that their 5th child will have at least one of these conditions? Here is the first step: 1. What is the cross? (Hint: You can use the 4 existing children to determine the genotypes of the parents.) O PpFF (female) x ppFF (male) O PoFf (female) x ppft (male) O pof female) x PPFI (male) O PPFF Ifemale) x ppFf (male) 2. What is/are the target genotypes? O pof OP.F. O pott O P.M 3. What is the probability the child will have PD AND cystic fibrosis? Answer to two decimal places (eg. 0.88). 4. What is the probability that their 5th child will have at…
