Answer:
It is almost impossible to totally eliminate recessive alleles from a population, because if the dominant phenotype is what is selected for, both AA and Aa individuals have that phenotype. Individuals with normal phenotypes but disease-causing recessive alleles are called carriers.
Explanation:
While harmful recessive alleles will be selected against, it's almost impossible for them to completely disappear from a gene pool. That's because natural selection can only 'see' the phenotype, not the genotype. Recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools.
