Which increases genetic variation?

Mutation.

Explanation:

The mutation increase genetic variation.

This mutation can be natural or artificial means man made. In genetic engineering, recombinant DNA technology also used to do mutation. The only mutation can bring significant changes in any organism.

All other processes of genetic variation do not carry as much as variation like mutation.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
