Can Two Right Handed Parents Have a Left Handed Child | Sykeena Jackson
Can Two Right Handed Parents Have a Left Handed Child? Yes, they can. As a matter or fact, my husband is left handed and both of his parents are righties. Although, inheritance may play a factor as I found out recently that his uncle is left handed on his father’s side.
A lot of research has been done into why people are right-handed, left-handed, ambidextrous. No simple answer has been found.
Approximately 90% of the population are right-handed, and inherited genes seem to play a part in this (hence my left handed husband’s uncle).
For example, University College London performed a study called “The genetics of handedness, cerebral dominance and lateralization.” They found that a child of two left-handed parents had a 26% chance of being left-handed — compared to a 19% chance if they had one right-handed and one left-handed parent, and a 9% chance if both parents were right-handed.
Twins have been the focus of much research, and the fact that identical twins can favor different hands suggests handedness is not a totally genetic trait. Hence the Olsen Twins. Mary-Kate Olsen is the twin who is left handed while her twin sister Ashley is right handed.
So we don’t know for sure why some people are left-handed, but we do know that even a child of two lefties is most likely to prefer their right hand.
