Summary Introduction

To determine: Whether a genetic disease caused by a mutant allele, in whichboth the affected parents  produce an unaffected offspring, can have a recessive nature.

Introduction: Genetic disorders are caused due to abnormalities in the genome of a person and these disorders are inheritable from the parents to the offspring. Genetic disorders can be autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, Y linked or mitochondrial disorders. In order to understand inheritence of human genetic diseases “Pedigree analysis” is considered the most efficient tool and it follows simple Mendelian pattern.
