- 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-linkedCould the characteristic followed in the pedigree be caused by an autosomal dominant disease? Why or why not? 3 4. O No, the offspring of 1-3 and I-4 contradict an autosomal dominant inheritance O No. the offspring of 1-1 and I-2 contradict an autosomal dominant inheritance O Yes, all individuals fit the autosomal dominant inheritance pattern ONo, the offspring of II-3 and -4 contradict an autosomal dominant inheritanceAutosomal Recessive Inheritance (trait only expressed if homozygous recessive)An albino man (nn) marries a normally pigmented woman (N_) who has an albino mother.
