Re: Albino HRP's in 2nd Gen?

Hi Grimbadger,
As far as I know, albino HRP's are completely white, but that fry is another variant known as leucistic - partial albinism.
Genetically speaking, if albinism occurs naturally in HRP's (which it probably does) it will be a recessive gene. It's perfectly possible to have a wild caught pair both of normal colour and both carriers of the gene for albinism. If they breed there's a 25% chance of albino offspring in the F1 batch. If only one of the wild pair carried the gene, there'd be no albinos in F1, but 25% would carry the gene and two of those carriers mated together would have a 25% chance of albino offspring in F2, and so on.
The odd colour of the fry would only be indicative of cross-breeding if this gene never occurs in wild HRP's as it would then have to have come from hybridisation. That said, there are a lot of hybrids going under the name of the HRP.
Both parents carry 2 genes for colour each of which can be
N ormal colour (dominant) or
A lbino (recessive). If they each carry a copy of the albino gene they will look normal but they will be genetically
NA. Each fry gets one of its genes for colour from each parent. So fry can be
NN - normal colour and not carry albino gene,
NA - normal colour but carrying albinism which can then be passed on,
AN - normal colour but carrying albinism which can then be passed on, or
AA - albino and will always pass on the albino gene. The leucistic gene is passed on on a similar way.
Did you get these from the chap on BCA who was selling a pair recently? I know his carry the albino gene as he mentioned it when selling fry, but as I said earlier, your's doesn't look like an albino, it looks like a leucistic variant.
