Which trait is affected by behavior ?
D.Attached Ear Lobes
The statement of this question is a bit confusing. All answers are an examples of an inherited traits which are received by an offsprings from its parents with the genes. Some human traits, such as eye color, height and attachment of ear lobes, vary over a wide range. Such ranges occur because these traits are governed by many genes (polygenic inheritance).Only the control of leaf shape has plasticity allowing responses to environmental conditions. When plants are exposed to weak light, most show a shade-avoidance syndrome, e.g., an elongation of the petiole and a decrease (sometimes increase) of the leaf blade area. This change in leaf shape provides for a better leaf position. Thus, behavior cannot affect this traits.
