Final answer:
The chance that the child of two carriers will have sickle cell anemia is 25%.
Step-by-step explanation:
The chance that the child of two carriers will have sickle cell anemia is 25%.
When both parents are carriers (heterozygous), they each have one normal allele (A) and one sickle cell allele (S).
The Punnett square for this situation shows that there is a 25% probability of the child inheriting two sickle cell alleles (SS), which results in sickle cell anemia.
It's important to note that there is a 50% chance that the child will be a carrier like the parents (AS), and a 25% chance that they will inherit two normal alleles (AA) and not have the disease.
