Final answer:
Mrs. Jackson's infant likely suffers from Epidermolysis Bullosa, a genetic condition causing fragile skin that easily blisters and tears.
Step-by-step explanation:
The hereditary disease that Mrs. Jackson's infant likely has is called Epidermolysis Bullosa (EB). This condition is characterized by extremely fragile skin that blisters and tears from minor friction or trauma. Such skin abnormalities in newborns can be quite severe, leading to secondary complications like infection, scarring, and in some cases fusing of fingers or other extremities as described in Mrs. Jackson's case. EB is caused by genetic mutations that affect the proteins responsible for skin structure and integrity, making the skin delicate and prone to injury.
