In this for Mr. Cha's 7th grade science. Improve and say Here if you are too. Anyways the answer is Multiple Alleles.
Its genetherapy.IM SMART!
When a normal allele is introduced into a virus, it is often referred to as gene therapy. This involves using the virus as a delivery system to transfer the normal allele into the cells of an individual with a genetic disorder, potentially correcting the underlying genetic defect.

Gene therapy
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
The probable genotype of this individual is likely heterozygous for the lethal allele, carrying one normal allele and one lethal allele. This individual is considered a carrier because they do not show any symptoms of the lethal allele's effects.
Recombinant DNA
An individual with a recessive disease-causing allele on one chromosome and a normal allele on the other chromosome is referred to as a heterozygote for that gene. Since the disease is recessive, the normal allele typically masks the effects of the recessive allele, meaning the individual usually does not exhibit symptoms of the disease. However, they can still pass the recessive allele to their offspring.
