Is handedness passed through genetics?
simple Mendelian genetics...right-handed is the dominant allele (R), left-handed is recessive (r). you can figure it out using a Punnett square. RR, Rr = RH kid rr = LH kid RR + RR = 100% RR -> all RH kids RR + Rr = 50% RR, 50% Rr -> all RH kids Rr + Rr = 25% RR, 50% Rr, 25% rr -> 75% RH kids, 25% LH kids rr + rr = 100% rr -> all LH kids to be LH, you have to have left-handedness somwhere in the family. however, you can be LH and neither your parents or grandparents would have to be.
Is righ-handedness dominant or recessive?
recessive...almost everyone i know is right-handed Population size does not always correlate with dominance and recessiveness. Dwarfism, which is dominant, is not prevalent in the population It could, however, be recessive, if right-handedness is dominant

How do the right and left brain work together?
Some background on the brain.The human brain is the focal point of the conscious mind. It is made up of 3 main parts, the cerebrum, cerebellum and brain stem. This big mass of neurons is divided into 2 hemispheres, the left and right hemispheres, that are linked by a large, bunch of nerves called the corpus callosum. Each hemisphere has its own functional specializations which correspond to neural mechanisms. The left hemisphere uses sequential, analytical and logical functions while the right hemisphere has more creative, holistic and visual functions. Left and right handed people use both sides of their brains. But, Left-handed people are known to use the right side of their brain more.
