"Hmmm... it occurs to me that one might use this to their advantage too. Being that the genes are sooooo close together that they effectively might be 'punnet squared' as a single gene, then by breeding 2 100% double hets for blizzard and tremper albino you would get nearly a quarter blazing blizzards, half 100% double het blizzard/tremper albinos and a quarter normals. This is basically 4x the chance (minus a very small fraction) that you would get by crossing most double hets.
Of course the hard part is getting the original 100% double hets for tremper albino blizzards in the first place."
No, you misunderstood me. Trait linkage makes it harder for recessive genes to be expressed because the DNA doesnt split as randomly as it would for genes farther appart. You are more likely to get the dominant genes to be expressed due to the linkage problem. The 100% hets are easy to get, once you get a pure homozygous blazing blizzard just breed it to a normal, or breed a blizzard to an albino. Its just hard to get the double hets to produce homozygous recessives, because the traitlinkage blocks the genes.
The easiest path for one to produce blazing blizzards would be through the Las Vegas line (rainwater). The tremper (texas) line is the next easiest, ands the Bell (florida) line is the hardest. I believe the odds were 1 in 100 changes of tremper blazing blizzards from double het breedings...? ----- Leopard Geckos 1.3
