An unusual cat with curled ears was crossed with a cat with non curled ears. All the kittens
born from that cross had non curled ears.
Later, when these offspring were crossed
each other, the phenotypic ratio was 3:1 non
curled to curled ears. What conclusion can be
made about the inheritance of curled ears?
