BETTAS by Jim Sonnier

BETTA GENETICS page 3...

RED COLOR IN BETTAS

In wild type Bettas Red is a layer of color that is just above the Black layer. The only other colors that can cover Red are the Iridescent Blues and Greens. The distribution of Red is limited to the pelvic, anal, and caudal fins. The color density is usually heavy in those areas. The normal distribution of Red color can easily be seen on most Multicolor Bettas.

RED BETTAS are also called extended Red because the normal Red pigment has been increased in density and extended in distribution to cover the entire body and fins of the fish. This mutant gene causes the Betta to appear to be solid Red in color. These are the brilliant Red Bettas that are so popular with fish keepers and breeders. The extended Red mutation is dominant over the gene for normal Red color. Some representative spawning results are presented below...

Yellow Plakat (short-fin) male

YELLOW BETTAS are also called Non-red Bettas. This mutated gene causes the formation of Yellow pigment instead of Red, or we can say that the Red pigment has been altered to Yellow. This mutation affects both normal Red and extended Red coloration. A Yellow (non-Red) Betta will have no Red pigment anywhere on the fish. The non-Red mutation is recessive to the gene for normal Red color. Some representative spawning results are presented below...

Spawnings for the non-Red (Yellow) gene
male parent female parent offspring
non-Red(Yellow) Multicolor(normal Red) 100% Multicolor(non-Red genotype)
non-Red(Yellow) Multicolor(non-Red genotype) 50% Multicolor(non-Red genotype), 50% non-Red(Yellow)
Multicolor(non-Red genotype) Multicolor(non-Red genotype) 75% Multicolor(67% non-Red genotype), 25% non-Red(Yellow)
non-Red(Yellow) extended Red 100% extended Red(non-Red genotype)
non-Red(Yellow) non-Red(Yellow) 100% non-Red(Yellow)
