A certain genetic disease is caused by a recessive allele. In the absence of effective therapy, homozygous individuals with this allele generally die before reaching sexual maturity. The allele also protects heterozygous individuals against several life-threatening viral diseases. If a medicine is found that provides a complete remedy for the disease, allowing individuals with the disease to live an entirely normal life, what will happen to the frequency of the allele in the population after that time ?
