The next three questions go together. Duchenne's muscular dystrophy (DMD) is a disease caused by a recessive allele at a gene on the X chromosome. Polydactyly is caused by a dominant allele at an autosomal gene. If a phenotypically normal woman who's father had DMD has a child with man who is heterozygous for the allele causing polydactyly but is otherwise normal, what is the probability that the child will have elther DMD or polydactyly, but not both? Part I: What is the cross? A ppxx x PpxDxD B- PPXPXX Ppx©y C- ppx"x x PpXdy D- ppxPx* x PpxDY Question 11 Part II: What is the probability the child will have polydactyly but not DMD?

Analysis of X-Linked Dominant and Recessive Traits The following is a pedigree for a common genetic trait. Analyze the pedigree to determine whether the trait is inherited as: a. autosomal dominant b. autosomal recessive c. X-linked dominant d. X-linked recessive e. Y-linked
The next four questions go together. Cystic fibrosis (f) and deafness (d) are caused by two unlinked autosomal recessive alleles, and colorblindness is caused by an X-linked recessive allele Xc. A female who is deaf and is a carrier for cystic fibrosis and colorblindness marries a male who is colorblind and is a carrier for cystic fibrosis and deafness. I. What are the female's and male's genotypes? II) What is the probability their first child is a phenotypically normal female? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). III) What is the probability their first child is a phenotypically normal male? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). IV) What is the probability their first child has all three conditions ? Enter your answer as percent without the percent sign to two digits (e.g. 12.34).
Answer 2 Duchenne muscular dystrophy is a sex-linked recessive disorder characterized by a progressive loss of muscle tissue. Neither Carla nor Rudy has Duchenne muscular dystrophy, but their first son does have it. What can you say about Rudy's or Carla's genotype in relation with the disorder? If the couple has a second child, what is the probability that he or she will also have the disease? Show your answers with a Punnet square.
The pedigree shows a family in which several members have suffered from one and the same disease (look at the picture to be able to answer) a) Is it a dominant or recessive allele that causes the disease? Motivate your answer. b) Is allele autosomal or sex-linked? Motivate your answer. c) What is the probability that III-3 and III-4 will have a healthy child? Motivate your answer.
Ann's family has a history of cystic fibrosis, a recessive genetic disease. In the pedigree, family members who are afflicted with the disease are shown in red. Members who are unafflicted may or may not be carriers. Which of the given family members can be identified definitively as unafflicted carriers of cystic fibrosis?
Bryan has albinism, an autosomal recessive trait, which means he is homozygous recessive for albinism and his genotype is aa. Bryan's parents, Frank and Amy, do not have albinism however they must both be heterozygous. Bryan's sister, Allice, is a carrier for albinism. If Allice has offspring with Jim, who has no family history of albinism, what are the chances that their offspring are carriers for albinism? What are the chances that they children will get albinism? Use Punnett squares.
Muffy, a color blind female with blood type A (heterozygous to type O) is married to Biff, who is also color blind and is homozygous for type B blood. Muffy has been having an affair with their gardener, Raoul, who is heterozygous for type B blood and has normal vision. Recall that color blindness is a sex linked recessive condition. Please help Biff's attorney determine the father of each of the children for the divorce proceedings. Show ALL work using punnett squares. a) female, type A blood, normal vision b) male, type O blood, color blind c) female, type AB blood, color blind
Please explain why sex linked recessive traits are inherited by the son from his mother. If a mother is a carrier, what percentage of her sons will have the trait? Please give me example of sex linked recessive trait.

A couple who are about to get married learn from studying their family histories that, in both their families, theirunaffected grandparents had siblings with cystic fibrosis(a rare autosomal recessive disease).a. If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c. If their first child has cystic fibrosis, what is theprobability that their next three children will be normal?
A couple seeks advice from a genetic counselor because they know that they are both carriers for cystic fibrosis (which is autosomal recessive), and the woman is a carrier for Duchenne muscular dystrophy (which is sex-linked recessive). For each of their future sons and daughters (calculate separately), what is the probability that they will be affected for: Cystic fibrosis Duchenne muscular dystrophy
