Plot summary

A pair of identical twins, Allen and George Carter, have been separated at birth as part of a twin study to settle the nature versus nurture question. Allen is raised on a highly developed Earth, while George has been raised in the provincial frontier society of Ganymede. On their twenty-fifth birthday, they are introduced to each other and given the task of running the family farm on Mars, where they have to work together in both day-to-day matters and unusual events. They find that they are forced to co-operate and also utilise 'primitive' technology in order to survive a major dust storm. After their initial mutual dislike, they develop a deep friendship.

Notes

After the story appeared, Scott Meredith, then a young science fiction fan named Scott Feldman, wrote to Asimov to point out a flaw in the story: Two characters were introduced in the opening scene, then never heard from again. This led Asimov to pay closer attention to the more mechanical aspects of writing.
