{'recessive gene': [0, 1, 0, 0], 'sex chromosome': [0, 1, 1, 0], 'rheumatism': [1, 1, 0, 0], 'muscular dystrophy': [0, 1, 0, 0], 'cerebral hemorrhage': [0, 1, 0, 0], 'nervous shock': [0, 1, 0, 0]}

Muscular dystrophy is a disorder that is caused by the expression of a recessive gene present on the sex chromosome. This group of inherited disorders involves muscle weakness and loss of muscle tissue, which worsen over time. The genes that produce proteins needed for muscle health and function are affected.

On the other hand, Rheumatism (Option 1) refers to a wide range of conditions characterized by inflammation or pain in the muscles, joints, fibrous tissue, or connective tissue. It is not linked to a sex chromosome-based recessive gene.

Nervous shock (Option 2), which is a common term for an acute stress reaction occurring within hours of a traumatic event, is also not caused by a recessive gene on a sex chromosome.

Cerebral hemorrhage (Option 4), a type of stroke that occurs due to bleeding in the brain, is a medical emergency and is not linked to a recessive gene present on the sex chromosome.

Hence, the correct answer is Option 3: Muscular dystrophy.
