Offspring of an African American and a European American Is Not Half Black and Half White

 There is a very common misconception that offspring of European American parent and an African American parent are half black and half white.  This stems from the following: Race (human categorization) A race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society.[1] The term came into common usage during the 1500s, when it was used to refer to groups of various kinds, including those characterized by close kinship relations.[2] By the 17th century, the term began to refer to physical (phenotypical) traits, and then later to national affiliations. Modern science regards race as a social construct, an identity which is assigned based on rules made by society.  https://en.wikipedia.org/wiki/Race_(human_categorization) Miscegenation Miscegenation (/mɪˌsɛdʒəˈneɪʃən/ mih-SEJ-ə-NAY-shən) is the interbreeding of people who are considered to be members of different races.[1] The word, now usually...

What I have noticed about ethnic groups is that there no clear definition of what they are.  That's what I am noticing in countries in general. In regards to Africa,  I am seeing names of specific ethnic groups like Wolof, Mandinka, Fulani being listed for certain countries, and those ethnic groups are in multiple countries.  I am also seeing nationalities being listed for ethnic groups like Somali for Djibouti. I am seeing the continental backgrounds like African, European for Cabo Verde which is where my maternal grandfather's paternal grandparents immigrated to USA from when it was still a Portuguese colony. Of course, there is stuff like Bantu, Berbers, Arabs for ethnic groups I see color race names listed for ethnic groups like White for Saint Helena, Ascension, and Tristan da Cunha. The color race names make no sens...
