Step by step
Solved in 2 steps
- A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?Hemophilia is another example of an X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia?Hemophilia results from a sex-linked gene. The disease is most common in males, but the hemophilia allele is on the X chromosome. Explain this apparent anomaly.
- 3) Queen Victoria of England, who ruled from 1837-1901, is believed to have been the carrier of hemophilia. Hemophilia is an X-linked disease in which the blood is unable to form clots. Please make a Punnet Square using the scenario below and answer the following questions. Queen Victoria married a man who did not have the hemophilia trait or disease. What is the likelihood that they would have a child with hemophilia? What is the likelihood that they would have a son with hemophilia? What is the likelihood that they would have a daughter with hemophilia?Lauren reports that she had a maternal male cousin (through a maternal aunt) and a maternal great uncle (maternal grandmother’s brother) both pass away from the same x-linked lethal condition. Both affected individuals did not have genetic testing. Lauren has a normal carrier screen for x-linked lethal conditions, which you know identifies 40% of causative mutations. If Lauren is currently pregnant with a male child, what is the chance that this child will have the condition?What is the karyotype for women who have an extra X-chromosome? Discuss all the ways you can test for this abnormality.
- Hemophilia is determined by genes on the X chromosome in humans. Assume that a phenotypically normal woman whose father had hemophilia is married to a normal man. 1) What is the probability that their first son will have hemophilia? 2) What is the probability that their first daughter will have hemophilia?The Xg cell-surface antigen is coded for by a gene located on the X chromosome. No equivalent gene exists on the Y chromosome. Two codominant alleles of this gene have been identified: Xg1 and Xg2. A woman of genotype Xg2/Xg2 bears children with a man of genotype Xg1/Y, and they produce a son with Klinefelter syndrome of genotype Xg1/Xg2Y. Using proper genetic terminology, briefly explain how this individual was generated. In which parent and in which meiotic division did the mistake occur?The allele for color-blindness is carried on the X chromosome. Making color blindness (a recessive trait) an X - linked trait. A colorblind make and a carrier female for color blindness. (But is not colorblind herself) have a child. Show your work! A) what is the % chance that their son will be color blind? B) what is the % chance that their daughter will be color blind?
- Men have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child. Complete parts a through d below. a. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a son will inherit the disease? nothing (Type an integer or a decimal. Do not round.) b. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a daughter will inherit the disease? nothing (Type an integer or a decimal. Do not round.) c. If a mother has one defective x…A man with red-green color blindness marries a woman who is not color blind. They have 3 children, one of which is a color blind girl. What is the genotype of the mother? Color blindness is an X-linked trait.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.
