Right-Handed Vs Left Handed

Human hand preference is predictably a biological and genetic (hereditary) phenomenon, but we see that 85 percent of people are right-handed.

Researchers have identified the specific gene (D Gene) that occurs more commonly among the population which responsible for promoting right-hand preference. The C gene, which is less likely to occur within our gene pool, creates a coin-toss chance of an individual being left or right-handed.
