Question

how does heredity affect flexibility? a. heredity does not affect flexibility. b. heredity affects which joint types a person develops. c. heredity affects the amount of flexibility present in joints. d. heredity affects how joint structure is developed.

Explanation:

Heredity influences the baseline range of motion and tissue elasticity that determine joint flexibility, while joint type and structure are primarily determined by basic anatomical development, not heredity as the primary factor. Option A is incorrect because heredity does impact flexibility, and options B and D misattribute the primary hereditary effect to joint type/structure rather than the degree of flexibility in existing joints.

Answer:

C. Heredity affects the amount of flexibility present in joints.
