In "To Kill a Mockingbird", what does Aunt Alexandra think about the importance of family and breeding?Aunt Alexandra

Aunt Alexandra felt that family and breeding were of the utmost importance. To her, heredity was a critically important topic. She maintained that the Finch family was better than most others because it had been there longer. In addition, she tended to label members of specific families according to their respective hereditary tendencies: one family has a predisposition to alcoholism, one has a predisposition to mental illness, etc. Family lineage was indicative of a person's moral and physical well-being, according to Aunt Alexandra.
