PATHOLOGY

Detailed explanation-1: -Cystic fibrosis occurs when both genes in the pair have a mutation. A person with cystic fibrosis inherits one CF gene from each parent. Cystic fibrosis is a genetic disorder caused by inheriting a pair of genes that are mutated or not working properly.

Detailed explanation-2: -Recessive diseases are single gene disorders that only occur in the homozygous state – when an individual carries two mutant versions (alleles) of the relevant gene.

Detailed explanation-3: -Cystic fibrosis is an inherited disease caused by mutations in a genes called the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

Detailed explanation-4: -Inherited disorders are caused by gene mutations. These include disorders such as cystic fibrosis, sickle cell disease, and Tay-Sachs disease.

Detailed explanation-5: -Parents of children with cystic fibrosis are more likely to experience anxiety, depression, or both compared to parents in general.
