Answer:
1. Attached
2. The have a 25% possibility of the disease and a 50% possibility of having the trait.
Explanation:
1. If J and K both carry the sickle cell trait, that means they are heterozygous for the sickle cell allele (Ss) where the sickle cell allele is recessive to the normal allele. The punnet square showing the possible genotypes of their potential offspring is shown in the attachment
2. The nurse would see that the genotypes possible are SS, Ss, or ss. SS would be a normal phenotype, Ss would be sickle cell trait, like the parents, and ss would have sickle cell disease. The ratios are 1 SS: 2 Ss: 1 ss. This means there is a 25% chance the child will be totally normal, a 50% chance they will inherit sickle cell trait, and 25% chance the child will have sickle cell disease.
