Betta fish marble gene.

If the solid colored parent betta carries the marble gene the percentage of marbled fry increases. Now let s say you breed 2 marbled betta. In fact marbling is pretty common. These patterns are not usually defined by colors and multiple patterns can appear on a fish making for a large range of possibilities.

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. You are bound to get at the least a quarter marbled fry. 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. 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.

Most black lace fish we see today come out of marble strains. Marble is a name for a transposon jumping gene. But they all carry the gene. There are no articles that prove or disprove this so let s talk about pigmentation and coloration in betta fish.

Patterns that appear on bettas are the result of gene s that modify the way pigment appears on the fish. Most black lace fish display too much iridescence in body and fins to be competitive in the black class and are instead shown into the dark bicolor class. 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.

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.
