Explain the f#'s for me

[WhispersinMyHead]

This is my understanding, thats why WC are F0.

This is what I found googling: The first filial generation seeds/plants or animal offspring resulting from a cross mating of distinctly different parental types
F1 means first filial generation. So with the above definition, a F9 x F5 of two different bloodline makes F1

Thats why all the rave about these "tags" are pretty much pointless...and for all we know (unless you caught it yourself) we have F4 that some sold as F1. So we go around selling them as F1 to the whole world. And also even WC could be from brother and sister is the waterhole is small enough, also as odds in life and nature goes it could happen, and sells as WC parents WooooHoooooo Yay Lotsa money for inbred WC.

Exactly why I could care less as long as they aren't siblings. As long as they look good.

To track gentics in the zoo/aquarium world F1 is the first out of the wild. You can't replicate F1 from anything that is already captive. F1 genes are highly valued, especially in species that are no longer able to be collected due to population status.

This is basic Mendelian genetics.
Biology 101


P1=F0
P=Parent
F=Filial

F0 are any 2 unrelated parents, wild caught or not doesn't matter for the definition.
They produce F1.
breed 2 F1 together ( ie: brother and sister) to produce F2, 2 F2 to produce F3
Any 2 unrelated ( ie: from totally different parents) F1 produce a new P1 generation or F0

So if i have an unrelated wc pair and they have pups what are the pups classed as? F1? Will all the parents pups then be F1?

 

[DB junkie]

So by defineition the ONLY way to obtain F2,3 and so on is by breeding brothers and sisters?

So these crazy F3 Hybrids we are seeing imported are really just products of several generations of incest?

And we're lining up to buy these things?

The more I know about breeding rays the less I wish I knew.

I really hope I'm misunderstanding this.

 

[keepinfish]

that is what it sounds like to me too DB. But i dont think everybody calls the f's the same thing. Look at the difference between zoodiver and DW's response.

 

[BayArea_510]

ii say f's are the generations from the wild, fo parents=f1 fry=f2 from breeding 2 f1's and so on

 

[Zoodiver]

I stand corrected. I went back to double check my info, what David posted is right. F1 is first captive born generation.

You do NOT have to breed sibilings to create subsequent F generations. You would use wild caught parents A's offspring and breed them with wild caught parent B's offspring. Diversity is important in genetics.... which is why so many are against hybid/cross species. It's hard to track bloodlines.
