What inherited condition results in fragile bones?

Osteogenesis imperfecta is the correct answer because it is a genetic disorder characterized by fragile bones that break easily, often with little or no apparent cause. This condition is caused by defects in the genes responsible for producing collagen, which is a vital protein that helps form and strengthen bones. As a result, individuals with osteogenesis imperfecta experience frequent bone fractures, bone deformities, and growth challenges due to the inherent fragility of their bones.

In contrast, osteoporosis is primarily an age-related condition that affects bone density and strength but is not inherited in the same direct manner as osteogenesis imperfecta. Paget's disease is a disorder that involves abnormal bone remodeling but does not relate to inherited fragility in a straightforward genetic sense. Osteomalacia refers to a softening of the bones due to vitamin D deficiency and is not a genetic condition, making it distinct from osteogenesis imperfecta.
