- An 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.In humans, the genes for red-green color blindness (R = normal, r = color blind) and hemophilia A (H = normal, h = hemophilia) are both X-linked and only 3 map units apart. Suppose a woman has four sons, and two are color blind but have normal blood clotting and two have hemophilia but normal color vision. What is the probable genotype of the woman? HR/hr Hr/hr hr/hR Hr/hR HR/HrClassical hemophilia is a sex-linked disease caused by a recessive gene on the X chromosome. (Hemophilia refers to diseases that cause delays in blood clotting.) If a woman who is acarrierof classical hemophilia has children with a normal male, give the ratios of the possible offspring with respect to classical hemophilia. Be sure to state both the genotypes and the phenotypes of each offspring. For genotypes, use X for a normal X chromosome, Xh for an X chromosome with the hemophilia gene, and Y for a normal Y chromosome. For phenotypes, if the offspring is female, be sure to state if homozygous normal, a carrier, or has the disease. If the offspring is a male, be sure to state if normal or has the disease.
- In humans, the genes for red-green color blindness (R=normal, r=color-blind) and hemophilia A (H=normal, h=hemophilia) are both X-linked and only 3 map units apart. Suppose a woman has four sons, and two are colorblind and have hemophilia and two are normal. What is the probable genotype of the woman? Group of answer choices HR/hr Hr/hr hr/hr Hr/hRWhat is a Barr body? How many Barr bodies in a person with genotype XXXXX? How is the structure of a Barr body different from that of other chromosomes in the cell? How does the structure of a Barr body affect gene expression? Color-blindness is an X-linked recessive trait. Heterozygous females are not color blind but they can sometimes have partial color blindness. Explain how this can occur.A human child is born with hemophilia (a condition in which the blood does not clot). Neither parent has hemophilia, and the gene whose (recessive) allele causes hemophilia resides on the X chromosome. What are the genotypes of the parents? (No explanations are needed.)
- Hemophilia is called "the royal disease" because many European royal families had members with the condition. Hemophilia is a recessive, X-linked disorder. Queen Victoria was unaffected by hemophilia, but was a carrier of the hemophilia gene (X X ). Suppose Queen Victoria's husband, Prince Albert, was affected with hemophilia (X Y). What is the percent probability that a son of Queen Victoria and Prince Albert would be unaffected by hemophilia? probability of unaffected son: What is the percent probability that a daughter or son of Queen Victoria and Prince Albert would be affected by hemophilia? probability of affected child: What is the percent probability Queen Victoria and Prince Albert would have two affected females? probability of two affected females: % % %B. The two rabbits with these corresponding genotypes were mated; CCch X CCh . Do the cross and answer the following questions. How many phenotypes will there be for the offspring? How about the genotypes? What is the percentage of agouti offspring to come out? What is/are the other phenotype/s of the offspring besides agouti?If a female who is a carrier of an X-linked recessive gene for hemophilia mates with a male who does not have hemophilia, what is the chance that their daughter(s) will be a carrier of the gene? O percent 25 percent 50 percent 75 percent
- , use the following information: type A hemophilia, a disorder in which blood does not clot properly, is governed by a recessive allele on the X chromosome. Suppose a healthy woman is a carrier and marries a man with hemophilia A, and they are expecting a child. Use XH = normal clotting, Xh = hemophilia. What is the chance the child will be male? What is the chance the child will be a male with hemophilia? What is the chance the child will be a female with hemophilia?Note: Don't copy from internet, Also answer correctly in terms of diploid, hemizygous, and carrier!! Thanks Explain why genetic disorders caused by recessive alleles of X-linked genes appear more frequently in males than in females? In your explanation, please include explanations of the following terms: diploid, hemizygous, carrier.In this part, you will work out on X-linked traits. Remember that males have only one X chromosome and females have two. For X-linked recessive, use the following designations: XA= normal Xa= the trait (a genetic disease or abnormality) For X-linked dominant, use the following designations: XA= the trait (a genetic disease or abnormality) Xa= normal Determine if the pedigrees below can be for a trait that is X-linked recessive. Write the genotype next to the symbol for each person in the pedigree below. A. Is it possible that this pedigree is for an X-linked recessive trait? B. What can you conclude about the children of mothers affected with an X-linked recessive characteristic? C. What can you conclude about the father of an affected female?
