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
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
