The tendency to hire those most like ourselves that has been cited as a reason for underrepresentation of women in sport leadership is known as:

This is called homologous reproduction. Homologous reproduction would suggest that since White males are in position of top leadership in school sport,there is a possibility that they hire White males.This theory of homologous reproduction would claim that people tend to be more comfortable with others that are like themselves. When it comes to hiring decision, they are usually biased about who to choose.

Hope this will !
