Is your sense of humor acquired through your environment or is it genetic? In a study done in 2000, a study was done trying to see if there was a genetic component to your sense of humor. The study was done using 127 pairs of female twins, 71 identical twins, which share 100% of their DNA, and 56 fraternal twins, which share only 50% of their DNA, were used. In the study, the set of twins were taken to separate rooms and shown the same comic strips. The twins were then to rate the strips funniest 0-10, 10 being absolutely hilarious.
The conclusion: the identical twins results were really no different than the fraternal twins. There was no difference to what the identical set of twins showed no real difference in what they thought was funny compared to the fraternal twins. Oddly, when it came to similarities among the twins, the fraternal twins were often closer to each other's answers than the identical twins.
This study helps to illustrate that there is no genetic factor to what people think is funny. It all depends on how the individuals grow up and not a magic "humor gene". Your sense of humor is all nurture and not nature.
