Which example shows an acquired trait, not an inherited trait?
Answer and explanation
Correct answer: Large muscles developed by exercise
An acquired trait develops during an individual’s lifetime because of activity, environment or experience and is not ordinarily encoded for transmission in reproductive cells. Exercise can enlarge muscles through training, so option B is the acquired example. Blood group, natural eye colour and pea seed colour are primarily determined by inherited genetic information. They are therefore distractors representing inherited characteristics rather than acquired changes.
