To answer this question, we can refer to psychological research on the heritability of personality traits, particularly those concerning the Big Five personality traits, which include openness, conscientiousness, extraversion, agreeableness, and neuroticism.
Studies on the heritability of the Big Five personality traits have been conducted using various methodologies, including twin studies, where both monozygotic (identical) twins and dizygotic (fraternal) twins are compared to determine the genetic contribution to personality. These studies have provided evidence that genetics plays a significant role in shaping our personality traits.
While exact percentages can differ based on the specific study or methodology, a general consensus in the field is that about 50% of the variation in personality traits can be attributed to genetic factors, with the rest being influenced by environmental factors and individual experiences.
Therefore, when looking at the options given for this question, the correct answer is:
D. 50
The research generally indicates that approximately 50 percent of the variation in the Big Five personality traits is inherited.
