DNA and personality traits study
Definition
A field of behavioral genetics research focused on identifying correlations between specific genetic markers and variations in human personality dimensions, such as those defined by the Five-Factor Model.
The scientific investigation into the extent to which temperament and character are heritable versus influenced by environmental factors.
Examples
The DNA and personality traits study finally explained why my brother inherited our father's stubbornness but somehow missed out on the gene for doing the dishes.
I told the lead researcher that the latest DNA and personality traits study better find a 'procrastination marker' soon, or I simply won't have time to read their results.
Modern science is truly a marvel, though I suspect the DNA and personality traits study will ultimately conclude that my love for reality TV is 90% genetic and 10% pure, unadulterated chaos.
