over copies
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Identifying the faulty Gene. Identifying the faulty Gene that causes the disease.

That process is called gene therapy. It involves inserting functional copies of a gene into the cells of a person with a genetic disorder to correct the genetic mutation causing the disorder.
A carrier is a person who carries a gene(most-likely for a genetic disorder) but do not have the trait controlled by the gene.
Sickle cell anemia causes sickle-shaped red blood cells. It is caused by a single base pair gene mutation.
A mutation in the gene makeup of the organism.
Typically, once a genetic disorder has been corrected in an individual through gene transfer, they would not pass the disorder on to their offspring. The corrected genes would be present in the reproductive cells and would be passed on without the genetic disorder.
This most commonly occurs if the disorder is recessive, meaning you must carry two copies of the gene which causes the disorder in order to show it.Everyone has two copies of each gene, one paternal and one maternal. If you only carry one copy (allele) of the gene which causes the recessive disorder and your other copy of that gene is normal, you will not have the disorder. However, you can carry it on if you have a child with someone else who also carries the gene which causes the disorder and the child gets two copies of the disorder gene.
One example is Huntington's Disease. With a recessive genetic disorder, to develop the disorder, you must inherit the gene from BOTH parents (odds, 1 in 4). With a dominant gene disorder, if you inherit the gene from ONE parent, you will develop that disorder (odds- 1 in 2).
Cystic Fibrosis
A genetic disorder is a health condition caused by an abnormality in an individual's DNA. These disorders can be inherited from parents or arise from spontaneous mutations. They can impact various aspects of a person's health and development.
