Question

which conclusion can be drawn from identical twins showing very similar rates of prosocial behavior when compared with fraternal twins?
a prosocial behavior is only acquired through the modeling process.
b there is no hereditary link with prosocial behavior.
c there is a possible genetic link to prosocial behavior.
d prosocial behavior is self - regulated so each person regardless of genetics will or will not partake in it.

Explanation:

Identical twins share 100% of their genes, while fraternal twins share about 50%. If identical twins show more similar rates of prosocial behavior, it suggests that genetics (shared genes) may play a role. Option A is too extreme (not "only" through modeling). Option B is incorrect as the data implies a genetic link. Option D ignores the genetic aspect shown by the twin comparison.

Answer:

C. There is a possible genetic link to prosocial behavior.
