PATHOLOGY

Detailed explanation-1: -Genetic disorders occur when a mutation affects your genes.

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.

Detailed explanation-3: -This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime. There are three types of genetic disorders: Single-gene disorders, where a mutation affects one gene.

Detailed explanation-4: -Chromosomal Disorder Some of the major chromosomal abnormalities are: Down’s syndrome-the addition of a chromosome 21 (trisomy) Turner’s syndrome-absence of an X chromosome (XO) Kleinfelter’s syndrome-addition of an X chromosome (XXY)
