What term means the degree to which people who are elected share features such as race

A race is a grouping of humans based on shared physical or social qualities into categories generally viewed as distinct by society. The term was first used to refer to speakers of a common language and then to denote national affiliations.

The Census Bureau defines race as a person's self-identification with one or more social groups. An individual can report as White, Black or African American, Asian, American Indian and Alaska Native, Native Hawaiian and Other Pacific Islander, or some other race. Survey respondents may report multiple races.

Explanation:

Historically, the concept of race has changed across cultures and eras, eventually becoming less connected with ancestral and familial ties, and more concerned with superficial physical characteristics. In the past, theorists have posited categories of race based on various geographic regions, ethnicities, skin colours, and more. Their labels for racial groups have connoted regions (Mongolia and the Caucus Mountains, for instance) or denoted skin tones (black, white, yellow, and red, for example).

However, this typology of race developed during early racial science has fallen into disuse, and the social construction of race or racialization is a far more common way of understanding racial categories. According to this school of thought, race is not biologically identifiable. Rather, certain groups become racialized through a social process that marks them for unequal treatment based on perceived physiological differences. When considering skin colour, for example, the social construction of race perspective recognizes that the relative darkness or fairness of skin is an evolutionary adaptation to the available sunlight in different regions of the world. Contemporary conceptions of race, therefore, which tend to be based on socioeconomic assumptions, illuminate how far removed modern race understanding is from biological qualities. In modern society, some people who consider themselves “white” actually have more melanin (a pigment that determines skin colour) in their skin than other people who identify as “black.” Consider the case of the actress Rashida Jones. She is the daughter of a black man (Quincy Jones) but she does not play a black woman in her television or film roles. In some countries, such as Brazil, class is more important than skin colour in determining racial categorization. People with high levels of melanin in their skin may consider themselves “white” if they enjoy a middle-class lifestyle. On the other hand, someone with low levels of melanin in their skin might be assigned the identity of “black” if they have little education or money.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
