Why Do They Say Not To?

[Ritingyou]

Ok so earlier this week I posted about getting my new boy Drake(Pk). Well another thing I figured out is he had a thing for one of my blue VT girls. So I figured why not give it a shot, since I dont really have goals for me first time in years since breeding..

But now some people are telling me that it would be a bad idea to let them spawn.. I guess it isnt to late to stop them if it is since shes still in the jar and he just now maybe an hour ago started building a nest. (Would have had it done about 8 hours ago but I didnt realize my heater wasnt working and he didnt like the colder water..oops)

Should I let them continue? Or should I stop them now?

the only reason we advice not breeding VTs is theres plenty of them sat in store/ in tiny tub on shelves left there to rot. They are considered the mutts of bettas i personally have no problem with VTs i wouldn't breed them however, most people these days prefer a more fancy type

 

[dipsydoodlenoodle]

I actually prefer VTs for the longer tailed fish and anything for PKs. But that is my preference and everyone is different.

Different tail types aren't recommended for breeding as their tails can sometimes come out less desirable.

 

[Ritingyou]

I see.. Well I guess it's ok then that he decided to stop making a bubble nest while I was sleeping. I never actually planned to breed them, but if they had an attraction for eachother who am i to stop them?

My halfmoon is attracted to my bigger VT and I gave him a shot. The girl is ready has her stripes and all and head down when ever he comes near her but when he does it's like hes saying "Ok so what do I do again?" LOL!

Thanks for explainging to me why most people say not to pair a VT and PK

its not kust VT with PK, I think its VT with anything...its genetics. VT is dominant over everything, so no matter what you breed a VT with, all fry will be VT

Exactly right. Vt is dominant so you'd get all vt fry from the original spawn. You'd have to breed ane of the fry with a non vt to have a chance at some other tail type.( the fry would ' carry' the non- vt gene but appearace wise would be vt).
simple genetics.

so as an example.....

VT dad x corwntail mum = all VT fry with crowntail gene
f1 cross...VT fry with crowntail genex crowntail= 50% (2:2) Vt tail fry with crowntail gene + 50% crowntail fry....VT gene gone
this trait is dominant
if you were to perform a f2 cross where vtct fry were crossed with vtct fry...eg, 2 fry from first cross

there would occur a 1:2:1 ratio on average of four where
1 fry is fully Vt:2fry are VTct( they look like vt but carry ct gene: 1 fry ct...look like ct with no vt genes

if a trait is autosomal dominant...all fry will by genetic dominant trait..all fry show VT .eg Vt.....if a trait is autosomal recessive 1:4 will be phenotypically ( they look like)recessive trait. if you cross a dominant trait with a recessive trait, a 1:2:1 ration occurs where 1 fry is genetically dominant and phenotypiclly dominant, 2 fry are phenotypicall dominant and genetically carry both genes, and 1 fry is phenotypically and genotypically recessive
hope you can understand that

 

[Ritingyou]

I wont lie, I got a head ache trying to understand that lol but I think I got it.. but does that go with the other tail types too? How do you know which is more dominate? Like.. right now im hoping to get a female delta.. which would be more dominate? the delta? or the pk? although that wasnt what I was planning.. i'm thinking about keeping her (because she has marble in her) for either casper or sunny which I found out is not a hm but a delta as well

 

[LilyRose Tank]

breeders haven't figured out how delta is inherited. but it would still be recessive to a vt.
you also have to think about colour dominance and recessive. as well as other dominances in tail shape...and fish size too

variegated fin is dominant to non variegated fin ( butterfly colouring)
extended red ( bright solid red) is dominant over normal red
black dominant over mose but alters where green and blue genes are involved
red loss gene is dominant over all over red gene...except extended red.....this gives a marble.
Double tail is recessive to single tail.
Halfmoons are a build up of different tail genes , although breeders havnt figured out what in total yet.....halfmoon x halfmoon wont give many halfmoom fry...usually less than 10%

this is just researched work....if anyone knows any different I would love to know for my own knowledge

when i remember where i had this info from, i shall post a link

getting back to vt and ct to help you understand





imagine a grid...a bit like a o's and x's game

ct ct...........mums two genes both ct

VT VTct VTct

VT VTct VTct ..........all fry VTct...veil tail type carrys the ct gene ( capital letters in genetics show dominance, small show recessive


dad genes
both VT


an f1 cross ( first generation cross between two fry from first cross



VT ct


VT VTVT VTct


ct VTct ctct

this shows 3 separate genotype ( what the genes say is present) Any VT gene will give a VT looking fish....ones with single ct gene is a carrier, the one with 2 ct genes is a ct

so in this instance 1:2:1 ratio is seen as
VTVT:Vtct:ctct
1 : 2 : 1

1 full VT
2 carrier VT
1 crowntail


hope that expalins it better

 

[loraxchick]

Look into Mendelean genetics. Lilly is right on. The ratios given are statistical averages. Not a rule. Actual outcomes will vary as far as what will be produced from any particular cross, with exception of the first cross which will produce 100% vt( assuming the vt parent carries only vt gene)

I remembered the link is from Jim Sonnier site
If anyone wants anything further explained, pm me, as I am a geneticist...I shall try to help anyone understand.

ratio for 1:2:1 = 25%:50%: 25%.....so technically 75% visual vt ( add 25 +50 from the ones with vt gene), 25% ct
