Both Nikon D5600 and Sony A68 have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another difference between these two cameras is that Nikon D5600's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the D5600 and A68 sensor size comparison.
Nikon D5600 and Sony A68 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
