Summary Introduction

To explain: The compatible pattern of inheritance in the given pedigree chart.

Introduction: Pedigree analysis is the symbolic representation of the presence or absence of traits in a particular family. The disease can be inherited with mitochondrial genes, sex-chromosomes, or autosomes. The pedigree analysis helps in determining the pattern of the inheritance of a particular disease.

If the disease inherited an autosomal dominant fashion, all the children of the next generation would be affected by the disease.

This disease condition is not Y-linked...
