Question

why are some people left handed??​

Answer 1

Answer:

Researchers who study human hand preference agree that the side of the preferred hand (right versus left) is produced by biological and, most likely, genetic causes. The genetic proposal to explain hand preference states that there are two alleles, or two manifestations of a gene at the same genetic location, that are associated with handedness. ... Individuals with the C gene will have a 50 percent chance of being right-handed and a 50 percent chance of being left-handed.

Hope it helps you..
