A genetic carrier (or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease.ickle cell anemia is the most common genetic disorder among African Americans in the United States. While approximately 8% are carriers, 1 in 375 African Americans are born with the disease.
[autosomal recessive inheritance chart: one parent a carrier] If both partners are are found to be carriers of the same disorder, there is a 25% risk with each pregnancy that the fetus will be affected by the disease. The chances are 50% that the child will be a carrier and 25% that the child will inherit no mutation. [autosomal recessive inheritance chart: both parents carriers] If a gene mutation is detected on one of the woman's X chromosomes, there is a 50% chance that her male children will inherit the disorder.
