Why are males affected by X-linked disorders much more oftenthan females?
X-linked disorders (like hemophilia) are more likely to affect people of one gender than the other. Which gender is this, and why are x-linked disorders more likely to affect people of this gender?
Females with a disease exactly mimicking X-linked agammaglobulinemia (XLA) have been found. Explain how this might happen?

- 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?arrow_forwardAn 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.arrow_forward(x-linked genes q7) Please answer this question for mearrow_forward
- (x-linked genes q8) Please answer this question for mearrow_forwardDiscuss why X-linked disorders are more common thanY-linked disorders.arrow_forwardHemophilia 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?arrow_forward
- 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?arrow_forwardConsider 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?arrow_forwardWhat is the karyotype for women who have an extra X-chromosome? Discuss all the ways you can test for this abnormality.arrow_forward
- Pls answer fastarrow_forwardNote: 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.arrow_forwardIf a father is affected by an X-linked dominant condition and the mother is normal, what is the probability of their children being affected? All sons will be affected. Half of the sons will be affected. All daughters will be affected. Half of the daughters will be carriers.arrow_forward
