I think i read a science article (possibly not actually science-backed) that said muscles on 1 side of the body grow if the opposite side does exercise to keep things in balance. So if you say exclusively did bicep curls with your right arm, your left bicep would still grow in size/strength to both physically balance you and also under the assumption that one day you might use the left for the same task.
