a.

Summary Introduction

To determine: The most likely mode of inheritance of the disease.

Introduction: Autosomal indicates the errors that happen on chromosome 1..22, preferably than on the 23rd sex-linked X chromosome. Also, the X-linked dominant genetic disorders concerning the 23rd X chromosome. Some models of autosomal dominant disorders are Huntington's disease and achondroplasia that is dwarfism.

b.

Summary Introduction

To determine: The genotype of each family member.

Introduction: The autosomal dominant inheritance model in an autosomal dominant disorder, the mutated gene is a dominant gene found on one of the nonsex chromosomes that are autosomes.

c.

Summary Introduction

To determine: Advice the three couples in the third generation about the likelihood of having an affected child as a family's doctor.

Introduction: Autosomal dominant is a feature or disorder that can be carried within families. In an autosomal dominant disorder, if one receives the abnormal gene from just one parent and can perceive the illness. Frequently, one of the parents also possesses the disease.
