Final answer:
The heritability of positive affect, negative affect, and well-being refers to the percentage of variation in these traits that can be attributed to genetic differences. Research suggests that traits such as well-being have a heritability ratio of more than 0.50.
Step-by-step explanation:
The heritability of positive affect, negative affect, and well-being refers to the percentage of variation in these traits that can be attributed to genetic differences among individuals in a population. While the exact heritability percentages can vary, research suggests that these traits have a significant genetic component. For example, the Minnesota Study of Twins Reared Apart found that traits such as well-being have a heritability ratio of more than 0.50, indicating that more than half of the variation in well-being can be attributed to genetics.
