Navigation property for recursive relations is badly named.

    //Properties
    public int PersonId { get; set; } // PersonId (Primary key)
    public string Name { get; set; } // Name
    public int? FatherId { get; set; } // FatherId

    //Navigation properties
    public virtual ICollection<Person> Fathers { get; set; } // Person.FK_Person_Father
    public virtual Person Father { get; set; } // FK_Person_Father

Fathers should be People.
