A newly identified mutation in mice,called "darkened dorsal," causes a dark stripe along the mouse's back.This mutation is located at a specific location on chromosome 2.A different sequence at this same chromosomal position results in a fur color pattern called "nonagouti." Based on this information,darkened dorsal and nonagouti are different

Question

However, it is not accurate to say they are mutations of the same chromosome or chromatids, as chromosomes themselves are not mutation events.
