01 Is left-handedness hereditary? In response to this problem, in 2007, scientist Clyde Franks announced that he had found a gene fragment called lrrtm1. This gene is the "originator" of left-handedness. Moreover, Franks' research also found that it is inherited from his father. Second, the reasons for the formation of left-handedness. Currently, the main reason for the formation of left-handedness is believed to be genetic. I believe everyone understands this. Many left-handers are actually born left-handed, including those who live in right-handed families. So I guess a lot of them were forced.
