Genetic disorders are illnesses brought on by deviations from the regular DNA sequence. These alterations, which might affect one or several genes, are referred to as mutations. One gene from each parent is carried by a person in a pair. The carrier of the genetic illness is the person who carries the mutant gene. There is a 25% probability that the kid will be born with the disorder if both parents are carriers of the gene linked to the genetic disorder.

There is a 50% chance that the child will carry the mutant gene if just one parent carries the mutation. The risk of having a kid with a genetic condition can be assessed via a test called carrier screening. Finding out if a healthy person possesses the recessive gene for genetic conditions including cystic fibrosis, sickle cell disease, and others is known as Carrier Screening.
