As the gene jumps between chromosomes it may alter the skin pigmentation of betta fish which can happen several times during their lifetime.
Betta marble gene.
Woke up this morning and he has some blue on him now.
When the jumping.
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.
Let s go back to the example of the royal blue betta.
I have a koi betta with the marble gene.
He arrived yesterday and his colors were black red and white.
But they all carry the gene.
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.
You are bound to get at the least a quarter marbled fry.
If the solid colored parent betta carries the marble gene the percentage of marbled fry increases.
In fact marbling is pretty common.
Marble is a name for a transposon jumping gene.
Marble betta fish as they re called in the industry have a type of jumping gene that can cause a natural change in the color of the fish.
When the jumping gene moves on the blue gene returns to its normal function and the blue pigment returns.
The blue gene was overridden by the transposons creating a loss of pigment.
He s beautiful but is.
Now let s say you breed 2 marbled betta.
I have discussed the marble gene in great detail here.
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.
Patterns that appear on bettas are the result of gene s that modify the way pigment appears on the fish.
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.
These patterns are not usually defined by colors and multiple patterns can appear on a fish making for a large range of possibilities.
Walt maurus and a handfull of other breeders started to breed the marbles for pattern and this lead to the distrubution of the marbles all over the united states.
This is what allows a marble betta to change continuously over the course of its life.
