A common genetic mutation causes a decrease in the crossing of the nerves at the optic chiasm in cats. These cats are still able to function normally by crossing their eyes. Why do they have to make this behavioral change?

e. To regain their peripheral vision

Explanation:

A common type of genetic mutation occurs in the cats that leads to the decrease in the crossing s of the nerves at the optics chiasm which is an X shaped strictures formed by the optic nerves of the brain.These fibers that travel through his are developed into a binocular vision and have an eye-hand coordination and temporal fibers remain ipsilateral i.e don't cross over.
