Which of the following traits is not inheritable? Ability to
taste P.T.C
roll the tongue

roll the eyeball
คำอธิบาย
Simply "rolling the eyeball" as a conscious gesture is not considered an inheritable trait, as it's primarily a learned behaviour and not directly coded in our genes; however, certain involuntary eye movements like "nystagmus" can be genetic and manifest as eye rolling in some situations, meaning there could be a hereditary component in specific cases related to eye movement.
