Anyone know of something fairly easy i can read up on as far as betta gens? or can explain it? wish i could remember that bio class XD


i have a white male (you can find the pics in the thread i made called 3 brothers) and a yellow female
i want to know what to expect as far as babies and if i should try to breed these two or try an other two
i also have a white female but she has purple in her fins. would it be better to use her to get WHITE babies? would some come out markingless? or for markingless should i try the yellow female (even though they may not come out white)

hope that made sense >_<

Hmm, I don't know much about bettas, but in school I loved genetics.
From what I remember white is a very tricky color, it's not a dominant.
The dominant colors in bettas are red and blue. I can't tell you which color would produce the whitest fish, but much of the fry's color will not only depend on the color of the parent, but also the parents of the parents, since some genes can lay dormant within the fish and only show up in the next generation.
Some info I found.
On yellow bettas
Info
info 2
28 articles

If these sites don't answer your questions you can always try looking into guppy genetics, I know those fish are being in many genetic studies.
Some color genes may be gender related, that's the reason only female cats are tabby and most red cats are male. I don't know if this counts for bettas though.
Good luck!

ok so
lemme see if this if right

yellows must have 2 recessive to be yellow
(the non red gene)

white betta also have the non-red gene
so if i breed the white and yellow i will end up with white or yellow babies

i could also breed a cambodian (light bodied fish with colored fins) with the white and get WHITE bodied babies with either white or colored fins since part of the white betta is being cambonian (lack of body color)

i could also breed two of my blues hoping that they may have black babies
assuming that both the parents have a recessive gene for being all black

When breeding the white + yellow, can't you get both white and yellow fry? And what about blue? Isn't that another dominat gene that may pop up when the dominant red is gone? (I haven't taken the timle to read the articles)
It would be really interesting if you manage to breed black bettas, they are supposed to be the rarest right?

You could try breedign all of them right? I'm really interested in the results ^^

yeah the yellow+white would give me a mix of yellow and white babies


the only way a fish can be yellow is if it has two recessive genes. if it had any dominant genes in its code it wouldn't yellow.
if it was Red/non-red the fish would be red not yellow
a yellow fish is non-red/non-red

i think if you breed red and blue fish you will get a mix of red and blue babies i think

I have a feeling red/blue would lead to many of the offspring having a red wash or a blue wash over their base color.
I often wondered if that was considered a negative thing in betta shows or not, because I find it very beautiful.

i was reading that in shows SOLID single colors are what they want. but i love marbled bettas and bettas with mixed colors in their fins. OH i picked up the black male over this weekend. he has electric blue in his tail and you cant rerally see it till he flares up. he's real pretty but i think the white ones are alot prettier than the black ones.

the guy who got me my black betta didnt even know there was a fish in the cup since it was on a black background XD

I never bred betta so I can't really say much. But according to genetics the color white is a broken gene so it would go much recessive. The marbled betta are a combination of colors thus they are a hybrid of some kind of dominant gene though on which side I do not know it could be very well be RRBB, RrBB, RRBb, or RrBb, if I was using reds and blues just as an example.

Yellow sounds like either a broken or recessive gene from what you guys said. Honestly the only way to find out is if you're CERTAIN that your solid color fish is a purebred, and the only way to do that is to mate it with a pure bred color female. If you get that pure color and only that color your male is a pure, if you get marbled he was a hybrid, if you got white/yellow, that might mean that both your parents were hybrids.

You may also have to be CERTAIN that your white/yellow is a pure recessive by breeding it with another white or yellow. If white/yellow really are recessive you will only get white or yellow, but if you get any other colors that means that white/yellow are hybrids as well.

I sounds like a lot of work and it probably is. But don't take my word for it. There are many other factors that work into. Such as white/ yellow with a tint of other color. That I'm not sure where that falls under.
