Detailed explanation-1: -Children of left-handed parents are more likely to be left-handed than are children of right-handed parents. However, because the overall chance of being left-handed is relatively low, most children of left-handed parents are right-handed.
Detailed explanation-2: -Although hand preference can be learnt, the genetic influence is surprisingly consistent. If two parents are right-handed, their offspring has a 10% chance of being left-handed.
Detailed explanation-3: -Left-handedness occurs in about 8% of the human population. It runs in families and an adoption study suggests a genetic rather than an environmental origin; however, monozygotic twins show substantial discordance.
Detailed explanation-4: -Since left-handed people are right-brain dominant, it enables them to creative and intuitive. They have high levels of imagination. Since they use their right hemisphere of the brain more prominently, this makes left-handed people more analytical, creative, and verbal, and showcase better language skills.
Detailed explanation-5: -The C gene is less likely to occur within the gene pool, but when it is present, the hand preference of the individual with the C gene is determined randomly. Individuals with the C gene will have a 50 percent chance of being right-handed and a 50 percent chance of being left-handed.
