- Analysis of X-Linked Dominant and Recessive Traits As a genetic counselor investigating a genetic disorder in a family, you are able to collect a four-generation pedigree that details the inheritance of the disorder in question. Analyze the information in the pedigree to determine whether the trait is inherited as: a. autosomal dominant b. autosomal recessive c. X-linked dominant d. X-linked recessive e. Y-linkedAnalysis of X-Linked Dominant and Recessive Traits A young boy is color-blind. His one brother and five sisters are not. The boy has three maternal uncles and four maternal aunts. None of his uncles children or grandchildren is color-blind. One of the maternal aunts married a color-blind man, and half of her children, both male and female, are color-blind. The other aunts married men who have normal color vision. All their daughters have normal vision, but half of their sons are color-blind. a. Which of the boys four grandparents transmitted the gene for color blindness? b. Are any of the boys aunts or uncles color-blind? c. Is either of the boys parents color-blind?Attached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.
- The pedigree of a family with haemophilia as shown in Figure below . If the gene for haemophilia is represented by Xh and the normal allele by X', write the genotypes of each individual in the pedigree. If the genotype cannot be determined with certainty write the possible alternatives.Number of FEMALE offspring that would have the condition of an X-linked trait, if an affected man and a carrier woman had childrenUsing the pedigree chart shown answer question . What is the likelihood that the progeny of IV-3 and IV-4 will have a widow’s peak?
- Give typing answer with explanation and conclusion Human ABO blood type is controlled by the I locus and has three possible alleles. The alleles which code for type A blood (IA) and type B blood (IB) are codominant, while the allele for type O blood (i) is recessive. In a cross between a person with a genotype of IAi and a person with genotype IAIB, what is the probability of having three offspring with type A blood?Give typing answer with explanation and conclusion Red/green colorblindness is inherited as an X-linked recessive trait in humans. A woman with normal vision, whose father was colorblind, marries a man with normal vision. Predict the color vision of their sons and daughters. Provide a probability for each offspring, depending on their sex. Write a pedigree consistent with this inheritance.The pedigree shows individual 1 and 2

Explain why it is useful for diagnosing monosomies and trisomies.This pedigree shows the segregation of a rare disease in a family. What is the most likely mode of inheritance of this disease?
