Which of the following is an accurate evaluation of the genetic influences on traits?

(a) data for the five-factor model give a complete portrait of personality.
(b) about 50% of the development of personality traits is attributable to genetic factors.
(c) traits can be used to effectively predict behaviors across different situations.
(d) genetic factors do not determine behaviors.

About 50% of the development of personality traits is contributed by the genetic factors. Option B is correct.

Genetic Factors of behavior:

Human is made up of DNA in which genes are present. These genes are responsible for the structural and behavior responses.

For example-

Therefore, about 50% of the development of personality traits is contributed by the genetic factors.

(B) About 50% of the development of personality traits is attributable to genetic factors.

Explanation:

It is difficult for scientists to definitely establish what the components of personality are. It appears that about 50% of the development of personality traits can be attributable to genetic factors. This has been seen in experiment conducted with identical twins. However, this also shows that there is an equally strong environmental component in the development of personality.
