The document contains Prolog code that defines facts and rules about the gender, fathers, mothers, and siblings of biblical figures. It defines predicates to display all males, females, and sibling pairs, as well as find specific relationships like a person's father, son, grandfather, or mother. However, the code intended to display females does not work correctly.

1. can someone fix this prolog code that does not display the female siblings?
