Grand Champion points are given to Best of Breed and Best Opposite (if they are champions) and to Select dog and bitch. The Best of Breed dog counts all of the Yorkies show. So say that if it takes 15 dogs to make a 5 point major and there are 6 class dogs, 5 class bitches, 2 dog specials and 2 bitch special - you received a 5 pt major(6+5+2+2= 15). If the BOS is a bitch and it takes 7 bitches to make a 3 pt major then, the BOS would receive a 3 pt major(5+2=7). Select Dog would receive a 3 pt major (6+1=7) Select Bitch would receive 2 pts (5+1=6)
Hope this helps.
Best of luck to you.
