How many Buddhist Lama reincarnations have been female?

As reincarnations can be from any condition or sex to any other condition or sex there is no reason to suspect that a female reincarnation of a lama is not possible. The Dalai Lama examines this potential eventuality in his discussion of compassion stating that you should not hate a person because in a pervious life he could have been the mother to you in one of your previous lives. For the vast bulk of people there is no knowledge ofwhat there previous countless lives have been.
