1.Random Amplified Polymorphic DNA Analysis of Genetic Diversity of the Geographical Populations of Hunan Betta
2.Yellow bettas are also called Non-red (NR) Bettas. This mutated gene causes the alteration of red pigment to yellow.
3.Butterfly bettas have the mutant gene that causes variegated fins with a very specific fin pattern.
4.The quest for the perfect halfmoon by selectively breeding for branching and straight caudal edges has given rise to a new development in the betta splendens tailforms - the Rosetail.
5.Specifically, a halfmoon betta must have a caudal where both ends are exactly 180 degrees apart or more, spreading towards the front.
6.Pastel bettas are identifiable by their softer, muted shades of color. In the Pastel betta, the colors lack the typical dark undercolor of the non-pastel forms of the same colors.
7.The color green in bettas is often synonymous with turquoise because the color usually has a blue tint.
8.Each of these color layers has its own genetic code which is determined by series of genes which combined eventually determine the color of the betta.
