An example of a genetic trait in humans is:
A
Being left handed or right handed.
B
Being happy or sad.
C
Having one brother and one sister.
D
Having a weight problem.
Explanation: 

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: -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-4: -Special or not, lefties are born, not made: Genetics are at least partially responsible for handedness. Up until last year, it was assumed that hand preference comes from asymmetrical genes in the brain-two hands, two brain hemispheres, one is dominant.

Detailed explanation-5: -Someone who is left-handed uses their left hand rather than their right hand for activities such as writing and sports and for picking things up. I noticed she was left-handed. There is a place in London that supplies practically everything for left-handed people. Left-handed is also an adverb.
