Technologically advanced humanoid civilization. The J'naii culturally suppressed their sexual
differentiation, having evolved beyond the need for separate sexual genders, and reproduced by incubating their young in fibrous husks
inseminated by both parents. Sexual liaisons were strictly forbidden under J'naii law. There were however, some J'naii who retained the
leanings toward gender, some male and some female. These J'naii lived in fear of being discovered and of being forced by the government to
undergo psychotectic therapy. The J'naii government requested Starfleet assistance in locating a shuttle vehicle lost in their star system
in 2368. The crew of the Enterprise-D provided equipment and personnel for the successful rescue mission. During the rescue, a diplomatic
incident was narrowly averted when a J'naii individual named Soren became romantically involved with Commander William Riker.
