Given a scientific passage and an answer, generate a question for the given answer.

Passage: Like bacteria, reproduction in archaea is asexual. Archaea can reproduce through binary fission , where a parent cell divides into two genetically identical daughter cells. Archaea can also reproduce asexually through budding and fragmentation, where pieces of the cell break off and form a new cell, also producing genetically identical organisms. Answer: fragmentation
Pieces of the cell break off and form a new cell in what type of reproduction that produces genetically identical organisms?
