chromosome inversion

Studies over many years have shown that natural populations of Drosophila are polymorphic for chromosome inversions.

Lattas, Chelsea K. Chromosome Inversions.

Some variants, and several chromosome inversions, consistently distinguish marine and freshwater populations, helping identify a genome-wide set of changes contributing to repeated adaptation of sticklebacks to marine and freshwater environments.

Chromosome inversion information for other smaller groups such as the antopocerus species group (Hawaiian Drosophila ) is published [ 13 ] , however DNA sequence data are not yet available for these groups.
