Question

Study the pedigree given and assign the type of inheritance of the trait.

Answer 1

As the trait skips generations, it is a recessive disorder. Also, as the female in the first generation transmits the disease to both male and female individuals in the fourth generation, it is an autosomal disorder. Hence, the given pedigree is that of an autosomal recessive disorder. Examples include albinism, cystic fibrosis, sickle cell anaemia, etc.
