Synteny describes the occurrence of genomic loci on the same chromosome; comparative usage often additionally concerns conserved neighbourhoods or order between genomes.

Rearrangements such as a chromosomal inversion can preserve membership of a block while reversing its internal orientation. The intended sense of conserved location versus conserved order should be stated. [ref]
