A theory suggests that genetics might play a role in determining the hand dominance. As per the theory, when a baby is developing in the womb, there are two forms of genes known as D and C, which the baby can inherit from its parents. If the baby inherits D gene from both the parents, then the baby will surely be right-handed. If the baby inherits D gene from one parent and C gene from the other, then the chances of baby being right-handed are much higher. However, if the baby inherits C gene from both the parents, then the baby will either be right-handed or left-handed. The chances are 50-50. Also, don t forget to subscribe to our YouTube channel.
