A genetic variant in a patient causes abnormal neuronal wiring in the fovea of the retina. Instead of the typical 1-to-1 synaptic relationship with bipolar cells, multiple cone cells converge onto a single bipolar cell, as shown in the diagram.
Which of the following describes the most likely physiological consequence of this mutation on the patient's foveal vision?
Decreased visual acuity, but increased sensitivity to low light levels.
Increased visual acuity, but decreased sensitivity to low light levels.
Decreased visual acuity, and decreased sensitivity to low light levels.
No change in visual acuity, but increased sensitivity to low light levels.
