Chapter 3, Problem 20P
For each pedigree shown,
a. Identify which simple pattern of hereditary trans-mission (autosomal dominant, autosomal recessive, X-linked dominant, or X-linked recessive) is most likely to have occurred. Give genotypes for individuals involved in transmitting the trait.
b. Determine which other pattern(s) of transmission is/are possible. For each possible mode of transmission, specify the genotypes necessary for transmission to occur.
c. Identify which pattern(s) of transmission is/are impossible. Specify why transmission is impossible.

It is inherited in an autosomal dominant and X-linked dominant pattern. The expression of AI disorder is determined by mutations in the autosomal alleles. One copy of the mutated allele (A) will cause the disorder. The severity of the disorder is determined by mutations in a gene carried on the X chromosome. Normal (or non-severe) abnormality (XN) is dominant over the abnormality (or severe) (Xn) allele. In the absence of the autosomal dominant allele, the abnormality gene on the X chromosome is notexpressed.

What are the applications of the genetics of blood typing? List at least three.arrow_forwardIdentify the specific mode of inheritance. 1.) Mae is affected with the disease phenylketonuria (PKU). The PKU gene codes for the production of the enzyme that metabolizes phenylalanine. Nonfunctionality of this gene can lead to intellectual disability, seizures, and other serious medical problems. 2.) Duchenne muscular dystrophy results from the mutation of the dystrophin gene. While both sexes carry the mutation, females rarely exhibit signs of the disease.arrow_forwardDetermine what is the most likely mode of inheritance of this disease (whether it is inherited as the result of an X-linked dominant or X-linked recessive trait). Use "A" for the allele associated with the dominant phenotype, and lowercase "a"" for the allele associated with the recessive phenotype. Write the most probable genotype for each individual based on the mode of inheritance you have determined.
