Right-handedness is considered to be a dominant trait, meaning that it is more likely to be expressed in individuals compared to left-handedness.
Left-handedness is considered to be less common than right-handedness, but it is not necessarily dominated by right-handedness. There is no clear answer as to whether left-handedness is dominant or recessive, as it is influenced by a combination of genetic, environmental, and cultural factors.

Left-handedness can have a genetic component, but it is not completely determined by genetics. Research shows that having one or both parents who are left-handed can increase the likelihood of a child being left-handed, but environmental factors can also play a role in the development of handedness.
