Betta Fish Marble Gene

Patterns that appear on bettas are the result of gene s that modify the way pigment appears on the fish.

Betta fish marble gene. So crossbreeding a marble and a solid colored betta fish will usually result in a spawn of mostly solid colored fish with a few marble patterned bettas thrown into the mix. Now let s say you breed 2 marbled betta. Because the marble gene is a transposon its color is unstable and often marble bettas will develop more or less color throughout their entire lives. The melano gene mm is a double recessive.

The black lace betta is a dark colored fish that rarely approaches the depth and intensity of the melano black 18. Most black lace fish we see today come out of marble strains. If the solid colored parent betta carries the marble gene the percentage of marbled fry increases. You are bound to get at the least a quarter marbled fry.

It is a partially recessive genetic so if you have a betta with the marbling gene and you breed it to a betta with no marbling genetics you might get a few marbled fry. A result of the. These patterns are not usually defined by colors and multiple patterns can appear on a fish making for a large range of possibilities. Displays of neurological condition.

The mm gene increases the black pigmentation in a betta meaning that you will finish up with a black fish. The absence of the bb gene creates a maroon colored fish of much darker color. There are no articles that prove or disprove this so let s talk about pigmentation and coloration in betta fish. But they all carry the gene.

The bb gene also comes into play with iridescent bettas making them appear much more pastel in color. Marble is a name for a transposon jumping gene. Well she sent in some photos of her betta fish and it became immediately obvious that she has a marble betta. A dna sequence that can change its position within the genome as a result marble bettas often have splotches of pigment or areas without pigment all over their body and fins.

A lot of people in the fish community seem to believe this is the origin of marbling but keep in mind 40 of the human genome are transposons and we don t really marble.
