Marshall and joe are brothers. both are very interested in board games and both are very intellectual. marshall is very kind and caring while joe is a bit of a nerd. what is the role that genetics has likely played in the personalities of the two brothers?

There´s an even split between genetics and life experience: both have shaped them.

Explanation:

Although personality traits are largely defined by our genetic composition, that´s not the only element to be examined. Personality is not determined by a single gene, but rather by the actions of many genes working together. Furthermore, both genetic factors and environmental circumstances are key elements in building our personality. Having a specific model of genes doesn’t inevitably develop a distinct trait, because some traits may happen solely in some settings.
