Let me say, that there really isn't a pure LH
I mean the papers may say 'pure' but after F3 gen, they are called 'pure'
Let me explain:
To make more LHs you take a 'pure' one and breed it to something you want to take genetics from (ie netherland dwarf for cute little itty bitty rabbits)
So you breed your 'pure' to the Nethie and get a F1 LH, which will be either Single or No maned babies, genetic can't be Double Maned
Then you take the babies from that litter that have the genetics you want and breed it back to a pure, thus F2 LH and some may (50/50) depending on genetics of the Pure in this breeding you will get double and single maned babies
Then yet again you breed those babies to yet another 'pure' to get F3 LHs (Again depending on parents 3/4 Double and 1/4 Single)
Then yet again one more time to a 'pure' and then you get a litter of pure LHs (Should be all Double Maned, as that is one trait you want to work towards)
Now not always does this stand true, I mean I have seen papers that have a F1 x F1 Breed and then there babies are F2, well that should be that way, they should still be F1s as they are genetically half LH half something else if not half LH, one fourth this and one fourth that.
As in a general standing the percent of LH blood in the rabbit makes the F gen number:
F1= 1/2 LH and 1/2 something else(s)
F2= 3/4 LH and 1/4 something else(s)
F3= 7/8 LH and 1/8 something else(s)
At the point of quote, unquote "PURE" is just the percent of something elses getting too small to come up, but you still have 'throw backs' of genetics (ie like breeding Harlequin rabbits and getting a REW in the nest box, but your rabbits are papered pure) I mean if you breed the F3 from above to a pure you actually get : 15/16 LH and 1/16 something else(s) and then that pure to another pure you get 31/32 and 1/32 something else(s) and so on and so on
Like a breeding of
F1 Buck (LHxMini Rex) x F1 Doe (LHxNethie) should = F1 litter (all either single or double as parents COULD not be doubles) and genetic speaking they are half LH, 1/4 Nethie, 1/4 Mini Rex, does that sound anymore more pure? NO!
Now, a breeding of
F1 Buck (LHxMini Rex) x F3 Doe (3/4 LH and 1/4 nethie) should = F2 litter (if buck is Single and Doe is Double maned, the litter geneticly should be 50/50) but still they are 5/8 LH, 1/8 Nethie, and 1/4 MR (I think that is right, my math maybe off sorry, but you see the picture)
Now if you want to breed, that is fine. I mean they are your bunnies, but please be aware of the standard people are trying to work towards. I mean I don't think I will EVER see Lionheads be reg. by ARBA as more then a COD Breed, but if they do, I don't want to see people get disappointed by what they thought was a good pure LH rabbit. As if any are Pure. They are some cuties though. Now if you want to breed them into pure LHs I would look for very typey rabbits that are either F3 Or Papered Pures to mix in with them. And of Course work towards and as close to the standard as possible, even if it is a Working Standard (Note, you can show only some colors, heck if I know which, but you can contact LHs National club for that info and working standard). Also, if they said they were LHs you most likely got F1 babies, which does happen to have No maned babies in litters, but with out papers you can't be for sure.
Again, SUPER CRAZY Cute Babies!!!! I demand more pics! I am a sucker for cute babies
