Question about Plakats

[ManyFISH4Me]

Hi,
I am thinking about buying a couple plakats. I have been doing a lot of reading about genetics. How do I know if the plakat I have can be breed without getting veils? (Like to a Dt, or HM fish)
THANKS

There is no way to completely eliminate the chance of getting veils. Selecting fish to breed that you know the history of is a good idea. Choose fish that don't have a lot of veils in their background.

Breeding plakats with plakats will give you 100% plakats... having short fins is a recessive trait, so if both parents have short fins, it means that they are homozygous for the trait and therefore can only contribute short fins to the offspring
Just be completely sure that your female is a plakat. If she's half plakat you'll get 50% plakat fry, but if she's long-finned you'll get 100% long-finned fry.

I mean breeding a plakat to a HM, or DT, or CT.

Oh, hehe, my bad )
Unless the HM, DT, or CT is half plakat, you'll get 100% long-finned offspring. I think CT is a dominant trait, so if one parent fish is CT, all the offspring should be CT or combtail. If you're breeding the plakat with DT, unless the plakat is half DT, you'll get all single tail offspring that carry the DT gene. If the plakat is half DT you'll get 50% DT and 50% single tail with DT gene.

I think I may have been confusing reading "long tail" as meaning Veil. So what I am getting out of all this, is that as long as 1 is plakat, and the other is NOT veil, I should not get any veil in the spawn. Am I reading correctly?
THANKS Everyone

Yep, that's it exactly

Well...actually, any strain of Bettas CAN at some point produce veils in breeding. Even delta x delta sometimes results in a veil. But they are few and far between enough that you don't need to worry about them.

Is it safe to assume that this is due to random mutation?

Also, I need to correct myself... I said CT is a dominant trait, but it's actually recessive. My bad )

Random mutation is a possibility, but I believe it's more along the lines of all our long-tails were developed FROM veiltails, so certain combinations can occasionally revert back to that, and you end up with the occasional veil.

Ah, what a bone of contention. For further reading enjoyment on this topic, I'll direct you folks here.


We went six pages on this very topic...

Well, random mutation is what causes genes to "revert back" in small numbers of individuals, so I'm going to go with that theory *lol*
If you only get one fry out of 200 that has an unexpected tail type, I can almost assure you it's a mutation (unless of course it's due to environmental factors and not to genetics at all.)
