Assume that the incidence of an X-linked recessive disorder is 1 in 200 male births. What is the frequency of the mutant allele?
Step by step
Solved in 3 steps
- Determine what is the most likely mode of inheritance of this disease (whether it is inherited as the result of an X-linked dominant or X-linked recessive trait). Use "A" for the allele associated with the dominant phenotype, and lowercase "a"" for the allele associated with the recessive phenotype. Write the most probable genotype for each individual based on the mode of inheritance you have determined. Show how all the partners are crossed and the expected offspring produced (You may use Punnett Square). OT I OT do IIAn individual with 46, XX genotype is diagnosed with Duchenne-type Muscular Dystrophy, a recessive X-linked disorder. Genetic tests confirm that this individual is a heterozygote for this disorder. Briefly, but specifically, explain how it’s possible that they are showing symptoms of this disorder.Duchenne muscular dystrophy (DMD), marked by muscular degeneration, results from an X- linked recessive gene. Thus, a female who is heterozygous for this gene and does not have the disease can be a carrier. What kind of offspring can you expect from a DMD-affected male and a carrier female? Can there be a carrier male?
- A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. a) How many of their daughters might be expected to be color-blind dwarfs? b)What proportion of their sons would be color-blind and of normal height? c)They have a daughter who is a dwarf with normal color vision. What is the probability that she is heterozygous for both genes?If an individual has the dominant phenotype for an x-linked trait, what is/are the possible genotype(s)? if an individual has the recessive phenotype for an x-linked trait, what what is/are the possible genotype(s)? Practice a Punnet square for each of the following autosomal combinations. Assume complete dominance. Determine the genotype and phenotype ratios of the offspring. Genotype ratio = _____GG : _____ Gg: ______gg. Phenotype ratio = _________dominant trait : __________recessive trait. parents with genotypes GG and Gg parents with genotypes Gg and Gg parents with genotypes GG and gg parents with genotypes Gg and gg Practice a Punnet square for each of the following x-linked combinations. Determine the genotype and phenotype ratios of the offspring. Genotype ratio = _____XGXG: _____ XGXg: ______XgXg:_______XGY: _____XgY. Phenotype ratio = _________dominant trait : __________recessive trait. parents with genotypes XGXG and XgY parents with genotypes XGXg and XgY parents with…Let’s suppose that two different X-linked genes exist in mice,designated with the letters N and L. Gene N exists in a dominant,normal allele and in a recessive allele, n, that is lethal. Similarly,gene L exists in a dominant, normal allele and in a recessive allele,l, that is lethal. Heterozygous females are normal, but males thatcarry either recessive allele are born dead. Explain whether or notit would be possible to map the distance between these two genesby making crosses and analyzing the number of living and deadoffspring. You may assume that you have strains of mice in whichfemales are heterozygous for one or both genes.
- A color-blind man marries a woman with normal vision whose father was color-blind. Remember that color-blindness is an X-linked recessive trait. Hint: see figure 12.7 in book. A) What is the probability that their first child will be a color-blind daughter? B) What is the probability that their first son will be color-blind?A man who is a dwarf due to achondroplasia and has normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplasia is autosomal dominant, and red-green color blindness is X-linked recessive. What are the possible genotypes and phenotypes of their children? What are the ratios for each? For full credit, you must show all work.A man who is a dwarf due to achondroplasia and has normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplasia is autosomal dominant, and red-green color blindness is X-linked recessive. What are the possible genotypes and phenotypes of their children? What are the ratios for each?
- Consider a couple: a woman who is homozygous for a recessive mutation that causes X-linked colorblindness, and a man with full color vision (he does not carry a copy of the mutation). a) What is the probability that a son of this couple will be colorblind? b) What is the probability that a daughter of the couple will be colorblind?The Delacour family is descended from the Veela race, a semi-human, semi-magical humanoid people reminiscent of the Sirens in Greek mythology with special powers. Imagine that being a Veela and having these powers is a X-Linked Dominant trait that is passed on genetically. (Hint: Use the Punnett Square.) What are the possible genotypes for Fleur and Bill’s daughter, Victoire? What are the genotypic frequencies related to the female children (in percentage format)? What is the likelihood (in percentage format) that Victoire would express Veela powers?In humans, the ABO blood type is under the control of autosomal multiple alleles. Color blindness is a recessive X-linked trait. If two parents who are both type A and have normal vision produce a son who is color-blind and is type O, what is the probability that their next child will be a female who has normal vision and is type O?
