Genes controlling left/right (LR) body asymmetry also influence handedness. Some genes associated with handedness or dyslexia are expressed in cilia.

Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast ...

Genes play a very small role in determining left-handedness ... - NPR

So in most people who are left-handed, there will not be a simple genetic explanation just running through the generations in a clear way.

The Nature of Being Sinister: The Genetics of Left-Handedness

As we shall see, genetics not only determines handedness, but also the body's left-right asymmetry and can potentially influence neurological ...

Consistent with previous meta-analyses, additive genetic effects accounted for about a quarter (23.64%) of the variance (95%CI 20.17, 27.09%) with the remainder ...

Left-Handedness Is Influenced by Early Life Factors

Only about 25% of the individual variance in handedness can be explained by genes, while 75% are determined by environmental influences. article ...

(2013) estimated the number of genetic loci involved in handedness to be at least 30–40, and possibly much larger. This estimation suggests that genome-wide ...

Left-handedness and its genetic influences are associated with ...

Shared genetic influences on hand preference and its specific cerebral cortical correlates. We found that polygenic disposition to left- ...

Handedness and its genetic influences are associated with ...

Roughly 10% of the human population is left-handed, and this rate is increased in some brain-related disorders.

Genes associated with left-handedness linked with shape of the ...

... handedness in the general population and linked their effects with brain architecture ... It identified some of the genetic variants associated ...

Left Handedness - an overview | ScienceDirect Topics

For example, perhaps what runs in families is not a handedness gene, but a genetic predisposition to increased exposure to testosterone, which then leads to ...

Genetic and Environmental Influences on the Handedness and ...

As to footedness, no genetic factors were observed in either sex. The effects of nonshared environmental factors were large (85%) in males and moderate (44%) in.
