    25%

    Explanation:

    In order to have sickle cell anemia, a person needs two S alleles. If there is even just one A allele, the person is a carrier but will not actually have it themselves. The punnett square shows that out of 4 offspring, 1 will have the SS genotype (Statistically). 1/4 is 25%.
