Yes
Yes.
If by "left brained" you mean, has a dominant left cerebral hemisphere, most people have dominant left cerebral hemispheres, which is why most people are right handed (note that the left cerebral hemisphere controls the right side of the body; the nerves cross to the opposite side). In a sense, I can agree with your statement, because most people actually are terrible at writing. But it isn't their left cerebral hemispheres which are to blame. It's just that most people don't care enough about writing to learn how to do it well.
Complete dominance
Yes, many of the functions you do with the dominant hand determines which side of the brain is more used. Be careful though, the right hand is controlled by the left side of the brain, and vice versa with the left hand.
While most left-handed individuals have language abilities located in the left hemisphere of the brain like right-handed people, some left-handed people can have language abilities in both hemispheres or in the right hemisphere. This variation in brain lateralization occurs due to complex factors and is not solely determined by hand dominance.
TRUE
Yes.
The brain hemisphere is located on the left side of the corpus collasum. This is responsible for regulating the activities on the right part of the body. Brain hemisphere is also responsible for speech and language functions.
The right hemisphere of the cerebral cortex is typically dominant in spatial tasks. It helps with tasks such as interpreting maps, recognizing faces, and understanding relationships between objects in space.
the left cerebral hemisphere
Handedness is caused by the dominance of one cerebral hemisphere over the other. Dominant right hemispheres cause left handedness (each hemisphere controls the opposite side of the body to the side it is on, since the nerves cross over). The exact reason why one hemisphere is dominant rather than the other, remains unknown. Quite possibly it is just an accident of fetal development.
The left cerebral hemisphere is typically superior in language processing, logic, and analytical thinking compared to the right hemisphere. It is also often dominant for right-hand motor control in the majority of individuals.
If neither are Dominant Or Recessive then its called co dominance or spuedo - dominance
The word dominance is a noun. It is the state of being dominant.

The left hemisphere is more logical and solves problems that require complex symbol manipulation. The right hemisphere evaluates sensory information quickly and makes "aesthetic" judgments.Since we usually direct our behaviour by making reasoned decisions, in those cases the left hemisphere is the controlling side, but experiments have demonstrated that split-second reactions are managed by the right-brain, which can respond better to what we perceive than to what we think.
