Genetics analyses using quantitative measures of handedness have demonstrated that genes involved in establishing left/right structural laterality play a role in controlling behavioral laterality. Therefore it is crucial how handedness is measured and it is clear that other genetic determinants remain to ...
Genetic regions associated with left-handedness identified and linked with brain architecture in language regions Science Daily - September 7, 2019 A new study has for the first time identified regions of the genome associated with left-handedness in the general population and linked their effects...
Familial data suggest that hand-clasping may be under genetic control: although the data do not fit any straightforward recessive or dominant Mendelian model, they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness and ...
There are forms of DNA that have been discovered to have other shapes, for example there occasionally arises a left-handed form of DNA that scientists have called “Z-DNA”. (Fortunately, Z does not mean zombie, however it is only a matter of time until a comic book writer uses it that...
Most scientists believe that DNA randomly arose as a right handed structure, and all DNA that has evolved since has had to follow that structure. DNA’s right-handedness may also be due to the Earth’s natural rotation, early human tire swing experimentation, or because our DNA is just too...
Differences between the right and left hand in ridge counts and pattern type counts were analyzed using data obtained from 711 families consisting of all parents and 2,466 children. Heritability estimates for each trait were derived from regressions of offspring on either parent or average value of...
Chamber muscle is formed on the outer surface of the primary heart tube in response to patterning information, and this process requires an endocardial signal from neuregulin 1, myocardial transcription factors Nkx2-5, Fast2 and Tbx2/5, and complex matrix components. The embryonic left–right...
Left-handedness and ambidexterity show small genetic overlap with each other45 yet are both phenotypically linked to neurodevelopmental disorders/cognitive abilities46,47. We report a significant genetic correlation between dyslexia and self-reported equal hand use, but not left-handedness, supporting ...
The items did not have the same categorical impact for the two groups of left- and right-hand writers. The behaviour of right-handers appeared globally more stereotyped. On the contrary, left-handed profiles were nearly all distinct. To explore these conclusions more thoroughly in the general ...
and in expressiveness ofbody language. [1] Meta-analysis of many different studies shows that women exceed men on measures of anxiety, trust, tender-mindedness, and gregariousness. Indeed, according to the researchers, “These differences are invariant across ages, educational levels, and nat...
