What is the genetic significance of humans being either left-handed or right-handed?
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
There does not seem to be any medical significance to being left-handed, but this is not true for medical professionals. They are keenly aware that left-handers often require more frequent and more complicated surgeries, as their bodies work differently than those of right-handers. Can you explain why this is so and what the implications are for medical care for left-handers?

The genetic significance of handedness in humans is still a topic of active research, as the exact
