Quizplus · Accepted Answer

Research has consistently shown that handedness is strongly influenced by genetics, with the majority of people being right-handed. However, the role of environmental factors in handedness development has not been completely ruled out. Handedness is not restricted to infants and can develop and change throughout a person's life. Identical twins are more likely to have the same handedness, but it is not always identical. Therefore, the best choice is B: influenced by genetics.
