QUESTION 4. Red-green color blindness is inherited in an X-linked recessive manner. Joe is red-green color blind. Joe's mother and father both have normal vision, but his mother's father (i.e., Joe's maternal grandfather) is color blind. All of Joe's other grandparents have normal color vision. Joe has three sisters (Patty, Betsy, and Lora), all with normal color vision. Patty (Joe's oldest sister) is married to a man with normal color vision; they have two children, a 9-year-old color-blind boy and a 4-year-old girl with normal color vision. Joe marries a woman who is a carrier of the color-blind allele; they are expecting their first child. Patty & her husband are expecting their third child. L4.9 Q4 Homework • Unanswered Which of the following scenarios has a greater probability of occurring and by how much? Scenario 1: Joe's first child will be a color-blind boy. Scenario 2: Patty's third child will be a color-blind boy.

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- ppxx x PpxOy OC OB O A OD Question 11 Part II: What is the probability the child will have polydactyly but not DMD? Enter your answer to two decimal places leg. 0.88). Question 12 Part II: What is the probability that the child will have either DMD or polydactyly, but not both? Enter your answer to two decimal places (eg. 0.88).
QUESTION 8 Consider the following pedigree. With no other information provided, what is the most likely mode of transmission (or mode of inheritance) of the allele for the unusual trait? sex-linked recessive autosomal recessive autosomal dominant sex-linked dominant
Question 10 Determine if the following statement is true or false. "Parents with the dominant phenotype cannot have offspring with the recessive phenotype." False, because both parents could be heterozygous. O True, because the dominant gene must be passed down from each parent. O True, because both parents have the dominant allele. False, because one parent could be heterozygous.
A couple who is heterozygous for simple recessive albinism (no epistasis here) plans on having 2 kids. What is the probability their children will have the same phenotype?
A couple is going to have a baby. They are concerned about sickle cell anemia, which results from having the homozygous recessive combination of the sickle cell gene ("s"), which produces abnormal hemoglobin. Having at least one normal version of the gene ("S") results in normal hemoglobin. The woman is heterozygous, and so is the man. What alleles does mom have? What alleles does dad have?
This is a modified question from the textbook, Campbell Biology in Focus (3rd edition), question #5 on page 256. A man with normal vision marries a woman with normal vision whose father was red-green color-blind (a recessive, sex-linked condition). Assuming that the woman's mother had normal vision and did not carry the recessive gene, what is the probability that the married couple will have a color-blind daughter? That their first son will be color-blind? That their second son will be color-blind? Include Punnett square for each question in your answer. You may find the below diagram helpful (the orange square means the individual has the phenotype of color-blindness, while the beige means the individual is a carrier of the mutated color-blind gene where XN and Xn represent dominant and recessive allele, respectively).
YOUR SISTER DIED FROM TAY-SACHS DISEASE, INHERITED AS A RECESSIVE ALLELE (t). you're married and planning to start your family. you're worried about the disease and decide to have genetic testing to see if you or your spouse is a carrier of the tay-sachs allele. the test results show that you're a carrier of the allele, but your spouse isn't. what is the probability that you and your spouse will have a child with tay-sachs disease? show your work.
young couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the percent probabilities for genotypes and phenotypes of the offspring.
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
A color blind (X linked recessive) female marries a normal male. What percent of her daughters will be color blind.
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).
