Species-specific description: Lu et al. (2023) "established a sws2a and sws2b knockout medaka model by CRISPR/Cas9 technology. We discovered that medaka sws2a and sws2b are mainly expressed in the eyes and may be regulated by growth differentiation factor 6a (gdf6a). Compared with the WT, sws2a-/- and sws2b-/- mutant larvae displayed an increase in swimming speed during the changes from light to dark ... . " (GMO) Seki et al. (2023) "used the CRISPR/Cas9-mediated knock-in approach to establish a transgenic medaka strain expressing the Chloromonas oogama channelrhodopsin (CoChR) in the ISL LIM homeobox 1 (isl1) locus. We demonstrated that light stimuli elicited specific behavioral responses such as bending or turning locomotion in the embryos and pectoral fin movements in the larvae and adults." (GMO)

Genetic engineering: Yes - in addition to the occurrence of natural variants, variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing
