PATHOLOGY

Detailed explanation-1: -Genetic disorders occur when a mutation affects your genes. Carrying the mutation doesn’t always mean you’ll end up with a disease. There are many types, including single-gene, multifactorial and chromosomal disorders.

Detailed explanation-2: -Some of the more common single-gene disorders include cystic fibrosis, hemochromatosis, Tay-Sachs, and sickle cell anemia. Even though these diseases are primarily caused by a single gene, several different mutations can result in the same disease but with varying degrees of severity and phenotype.
