Correct Option: A
The correct answer is Option A
If both partners have the AS genotype, they should not marry as their children may inherit the sickle cell anemia gene and have the SS genotype, or they may inherit the AS or AA genotype.
When an individual with the AA genotype marries someone with the AS genotype, their offspring can have either AA or AS genotypes, which is considered favorable.
