Syntenic
Synteny refers to the conservation of blocks of genes on the same chromosome across different species. In comparative genomics, syntenic regions are segments where a set of neighboring genes remains linked on a chromosome in two or more species, reflecting shared evolutionary ancestry. The term can describe either the general notion that genes reside on the same chromosome across species or the more specific concept of syntenic blocks—clusters of genes whose relative content is preserved, though not always in exact order.
A related concept, collinearity, denotes a stricter condition where both the content and the order and orientation
In practice, identifying syntenic regions aids genome annotation, reconstruction of ancestral karyotypes, and transfer of functional
