For personality differences that cross cultures, I can give an example of a racial difference that is also one of these cross-cultural differences.  One way to think about this is that there are different values attached to certain traits in different cultures.  In the US, being cheerful and talkative is a valued trait, and other cultures might value being quiet and cautious.  To be more specific, white Americans might value talkativeness in the same way black Americans value quietness, but black Americans might not value talkativeness.  The traits you might expect in someone from a certain culture also tend to be different from the traits you would expect in someone from another culture.

One way to think about personality differences is to notice that they tend to be visible across cultures.  There are ideas that all cultures have about what is good or bad, and these ideas tend to differ from culture to culture.   I would say that there are some personality traits that are more common in some groups than in others.  People who tend to share particular ideas about right and wrong, or people who tend to be more polite or not, are likely to grow up in a culture that supports these ideas.  So black people tend to come from cultures that are more likely to support them learning these ideas, and white people tend to come from cultures that are more likely to support these ideas.

in what ways culturally are white people and black people different?
user
A few ways to think about this is that both black people and white people belong to the same human race, and that race does not mean the same thing to both of these groups.  White people, since it is a word for a group of people, have some shared characteristics.  In terms of group attributes, one might say white people tend to be tall or light skinned.  In contrast, one could also list characteristics that white people do not share with black people, and these would be more like “lack of ability to do a certain skill”, or “tendency to vote for a certain political party”.

are there any personality differences that come from their heritages?

One way to think about this question is to divide it into three pieces.  We could start by saying “there are personality differences between people from different cultures”.  This is just an assumption about human psychology.  Cultural differences can have an effect on how people think, and on what they value, and their personalities can be affected by this, too.  Another way to think about personality differences is to notice that they tend to be visible across cultures.  There are ideas that all cultures have about what is good or bad, and these ideas tend to differ from culture to culture.   The third way to think about this question is to look at personality differences within a specific culture, like within a single family.  Since parents pass on their cultural beliefs and values to their children, a child is more likely to take on their parent’s personality if their parent also grew up with the same cultural beliefs.
