Marble is most likely a partial dominant*, so crossing a marble to a solid-colored fish will usually give you mostly solid-colored fish, with perhaps a handful of marble-patterned. If the solid-colored parent carries the gene for marble, your percentage of marbled fry is increased. The marble gene affects the solid color in unpredictable ways, making new color combinations and patterns possible. However, the breeder will probably have to go through several generations (and many culls) before attaining what he or she has in mind, and after that is faced with the challenge of getting the new color to breed true.
Breeding marble to marble will usually get you some dark-bodied solids, some light-bodied solids, some butterfly, and some marble. The solid-bodied butterfly from a marble spawn will have the same inherent characteristics of a solid color that comes from a marble line; when the butterflies are bred to the same solid color that comes from a solid colored line, the fry will all carry a butterfly partial dominant gene.
Spawns of either light bodied solid color or dark bodied solid color Bettas from marble stock will produce some marble, some solid color and some variegated fish. If the marble genes are introduced into a stock of true-breeding solid colored fish then it becomes extremely difficult for the breeder to return his stock to the pure-breeding solid colored type. The fish generally seem to always throw some marbles or parti-colored
fish. A cross of a marble stock fish of one color type can produce the marble effect in the color of a fish of a non marble type.
Grizzled bettas are usually pastels with an amount of "grizzle", or colored flecks, on the body. This pattern is generally set, and isn't prone to change like marbles.
