This is a good choice if your priority is to get all the answers quickly. Recessive diseases are caused by changes mutations in the genes of a person, All people have two copies of each gene, one inherited from each parent. A recessive disease occurs when two copies of the same gene suffer a mutation. A carrier is a person who must read meaning in hindi only one mutated gene and the other defechs is not affected.

Carriers usually have no symptoms and do not know they carry a mutation. Fragile X syndrome is an example of this. Even without a family history of disease, however you can be carrying.

What do they recommend? What is a recessive disease and what a carrier is? What is a carrier screening? A carrier screening analyzes the genes of a person to determine if that person is a carrier of what is recessive gene defects recessive genetic disease. A screening can detect many, but not all carriers of a disease. I do not have a family history of disease, should I do the screening anyway? How I can make screening?
