Breeding GBA and common bristlenose?

[A-town...]

Before everyone starts moaning about crossbreeding I already know you shouldnt ect. :bounce:

All I want to know is if you cross a gba with common bristlenose what % will be golden what % will be brown?

Also Albino cross GBA

And Albino cross common bristlenose?

Dont know much about genetics.

Thanks in advance!

There are some cross breds for sale on trademe ATM

It depends on which are dominant and recessive....

Albino and lutinos are usually recessive so I Think that for the first generation you should get all or most of the fry being the brown but carriers of the albino/lutino gene then after that you should get 25% brown 50% Brown carriers then 25% fully GBA's/Albinos

regarding BNs can we get Calico ones in NZ??

ive been looking for some splotchy golden ones.

All I want to know is if you cross a gba with common bristlenose what % will be golden what % will be brown?

simply put; hard to say m8.

ive seen some gba's with a splotch of brown. that could possibly indicate that brown / black skin colour is not completely dominant over golden.

however i dont think there browns with red eyes, as albinism is usually a totally recessive trait.

I have read somewhere the golden colour in females is more dominant in the males is this correct? so if this is correct say I cross normal male bristlenose with golden female is there higher chance of throwing golds or not nessacerily?(sp.)

If it was true (which i doubt...) then you are probably more likely to get golds in your first spawn, but i doubt it unless the EDIT:gold colouring is partly linked/linked to the X chromosome somewhere.....

golden colour in females is more dominant in males?

what do you mean?

nick it has nothing to do with albinism.

I couldn't think of another word

he means that it you were to cross a female golden with a male normal you could be more likely to get gold colouration than if you were to cross a brown female with a gold male

[phoenix44]

that would happen if golden was x-linked and dominant over brown.

its all hypothetical any ways. can't say what the offspring would look like without knowing for certain what the parents genes code for.

GBA L44 comes from Paraguay where a amelanistic wildcaught male was crossed with 'normal' female, and line breeding has continued the trait by breeding in the amelanism.

Any GBA from GBAXGBA cross with the brown spot or splotch is often just showing a glimpse of their distant origin.

I would think any pairing as you've described could possibly produce an array of young from brown to golden

although as far as I'm aware the amelanistic trait is not dominant as suggested

black eye would be more dominant than albino. any day.

sweet.

I put a male albino with a female GBA, the fry are now 5 days old and all appear to be brown :-?

Ive heard of that happening before except they would get the odd albino.

I may be completely wrong here but I have been told that if an ordinary brown bristlenose is crossed with a gba or albino bn that the spots will be a lot lighter than the normal brown bn.
