What is the genetic significance of humans being either left-handed or right-handed?
The genetic significance of humans being either left-handed or right-handed, also known as being sinistral or dextral, has been a topic of research for decades. being left-handed means using the left hand dominantly for doing various tasks, while right-handedness refers to the use of the right hand dominantly.

Although the exact cause of handedness is not yet fully understood, it is now generally accepted that there is a genetic basis for it
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
