Genetic Analysis: An Integrated Approach (3rd Edition)
- Achondroplasia is a rare dominant autosomal defect resulting in dwarfism. The unaffected brother of an individual with achondroplasia is seeking counsel on the likelihood of his being a carrier of the mutant allele. What is the probability that the unaffected client is carrying the achondroplasia allele?arrow_forwardState whether each of the following genetic defects is inherited as an autosomal recessive, autosomal dominant, or X-linked recessive trait: phenylketonuria (PKU), sickle cell anemia, cystic fibrosis, Tay-Sachs disease, Huntingtons disease, and hemophilia A.arrow_forwardautosomal recessive allele (not sex-linked). Omplete the following monohybrid crosses for different types neritance pattefh autosomal dominant, sex linked recessive, and dominant inheritance. Inheritance of autosomal recessive traits Female parent phenolype: Example: Albinism Albinism (lack of pigment in hair, eyes and skin) is inherited as an Male parent phenatype: Using the codes: PP Pp (normal) (albino) la) Enter the parent phenotypes and complete the Punnett square for a cross between two carrier genotypes. A Give the ratios for the phenotypes from this cross. Pp (carrier) eggs sperm Phenotype ratios: Inheritance of autosomal dominant traits Example: Woolly hair Woolly hair is inherited as an autosomal dominant allele. Each affected individual will have at least one affected parent. Using the codes: WW (woolly hair) Female parent phenotype: Male parent phenotype: Ww (woolly hair, heterozygous) W w (normal hair) (a) Enter the parent phenotypes and complete the Punnett square for a…arrow_forward

A recessive mutation in this gene causes the most common type of hemophilia; it is known as hemophilia A. If this gene is mutated in the hemophilia, but it will always cause this type of hemophilia if mutated in the This is because have two X chromosomes; since this is a recessive mutation, more than likely the other X chromosome has the normal gene.
