plural ohnologues · alternative ohnolog
- biologyOne of a pair of paralogous sequences that result from complete genome duplication.
In the regions surrounding the TRE genes on scaffolds av458 and av6, synteny was well preserved (Fig 1B ), suggesting that AvTreA-A’ and AvTreC-C’ were ohnologues and form a quartet of four homologous regions (as in Hur et al and Van Doninck et al).

According to P. P. Singh and colleagues, this term was coined as an eponymous tribute to Susumo Ohno (1928-2000), who first proposed that whole genome duplication may play a crucial role in evolution.
