What is the genetic significance of humans being either left-handed or right-handed?
Left-handedness and right-handedness are traits related to preferred use of the hands, and the genes that influence these traits have not been conclusively identified. However, recent studies suggest that there are likely multiple genes that contribute to handedness.

There are several theories about the genetic basis of handedness. One theory is that the genes involved in brain development and lateralization might influence handedness. Studies have identified several genes that have been associated with hand preference in certain
As far as I understand, our handedness is determined by a couple genes, but it does not seem to play any significant role in our actual traits or abilities. If we are talking about other species, the handedness may have a more significant role through evolutionary biology. Is this correct?

Yes, you are correct that in humans, handedness, which is usually determined by the preferred use of one hand for most activities, is influenced by genetics. Specifically, there are
