Guppies

[thefishykid]

i have and love my gupies. but whati want to do is create a pure gene. i did read up on this but only got the outlines on how to do this. i have a pure black male that i bought and very dark female. is this true if i breed these fish then interbreed with the young. will my female guppies become black the same as the male?. or do tou get a lot of problems interbreeding. i have heard that this works but want more advise on this before i try and start trying it

Inbreeding, e.g. young male guppies with their mother, is how breeders have created and maintained the colour strains they want. The downside is that if there are any genetic defects, you are doubling the chances of it being inherited by the offspring. This is one of the reasons why guppies are a much weaker fish than they were 30 years ago. When you inbreed you do run a much larger risk of deformitites and other genetic effects. Having said that, it probably will not be very apparent in the first generation, but will increase with each successive generation- and a lot of the fish you buy from an lfs are already siblings, perhaps the offspring of siblings.

There is a thread on page 2 in the livebearer section at the minute asking about creating a new strain of guppy which you may find some use

Linebreeding is breeding offsprings with the parents. From what I understand about linebreeding discus, it would take 7 generations to create a pure strain. Pure meaning that you will have more than 50% of the offsprings turning out like the parents.

so then it will take a long time to do this good job i am patient

It's going to be hard, let me warn you. Many Guppies are very inbred anyway, especially blacks and fancy colors like that. To get that far in inbreeding to get a pure line is going to give you lots of deformed fry. They usually really start cropping up after 5 generations. I'm not sure you could even get to fish that will produce healthy fry by then...

If only Guppies weren't so Fancy and Inbred....

 

[demonmagus]

you could try and get the guppies which are more 'ordinary' looking
