3. The tribe that favours boys

A certain tribe favours boys so much that every family in the tribe keeps on having children until they have their first boy, whereupon they stop.

A visiting anthropologist remarks that the tribe must be overrun with girls since there must be many families with many girls and one boy but no families of the opposite composition.

Is he right?
