Dizygotic twins, and monozygotic twins are respectively 8.5 percent, 14 percent, and 14.5 percent. This information has led to the hypothesis due to prenatal difficulties, twins have a higher prevalence of left-handed.
Is left-handedness more common in twins?
However, nearly all research that looked at the prevalence of twins in the general population revealed that twins had a higher probability of left-handedness than singletons (Vuoksimaa et al., 2009). Similar to other human characteristics, handedness is complicated and appears to be impacted by a variety of elements, including genetics and environment.
The tendency to be more skillful and at ease using one hand instead of the other for tasks like writing and throwing a ball is known as handedness, or hand preference. In Western nations, 85 to 90 percent of people are right-handed, while 10 to 15 percent are left-handed, despite the fact that the number varies throughout. It's rare to be both ambidextrous and mixed-handed, which refers to the preference of one hand over the other for certain jobs.
