In an ocular dominance histogram, which pair of columns would be most likely to show the strongest combined representation in alternating strabismus?

• A. 1 and 2
• B. 1 and 7
• C. 3 and 4
• D. 2 and 7

Answer: (B)

In alternating strabismus, the eyes take turns being favored, so the ocular dominance pattern shows two distinct strong representations—one from each eye—across the spectrum. In the histogram, the columns at the far ends represent complete or strong dominance by each eye. The strongest combined representation, then, comes from those extreme columns because they reflect both eyes achieving dominance at different times. The other pairs, which sit closer together on the scale, would indicate more similar or intermediate levels of dominance and wouldn’t capture the dual strong representations seen with alternating dominance.
