What has research found about the heritability of traits identified by trait theories?
A) Traits only show heritability for family members who are raised in the same household. Otherwise there is no type of research that can investigate personality heritability.
B) Traits only show heritability for identical twins, since they are genetic clones. Relatives without the exact same genetic heritage show no real personality heritability.
C) Traits tend to be heritable, as demonstrated by the fact that the closer two people are genetically, the greater their trait similarity.
D) Personality is 90% genetic, so those who don't want to turn into their own parents are out of luck.

Question

Research has consistently found evidence for the heritability of personality traits, with the degree of heritability increasing as genetic relatedness increases. However, heritability estimates vary depending on the specific trait and the population being studied. It is important to note that heritability does not mean that traits are predetermined and cannot be influenced by environmental factors.
