There is a strand of Jewish tradition which regards God as being hermaphroditic, so that when Adam was first created, he had both physical attributes. It was only later when Adam desired a companion that the original being was divided into two sexes.

The description is also "in his own image and likeness" translating two different Hebrew concepts. The implication of "likeness" is that God left creation uncompleted, and passed the responsibility to mankind, as also stewardship.
