Question 28
To what extent do genes determine which hand we use to pick up our morning cup of tea or coffee? Around 90% of the human population uses their right hand. Researchers examined rare genetic variants in the genetic data of more than 350 000 individuals to search for clues about what influences handedness in humans. Their findings suggest that a type of protein involved in early brain development before we are born affects whether we are left-handed or right-handed.
In groups, plan and investigate the variation in handedness in your class.
