Dear Oksana! Gemeralopija ("night blindness") is inherited under different schemes or plans and depending on it or this has a various etiology. By a fragment of your family tree, in this case takes place to be a pathology of a receptor part of the rods, inherited on the dominant or prepotent scheme or plan, and your son theoretically cannot have gemeralopii, as you not a carrier or bearer of the given dominant or prepotent gene.
