Sugar Glider genetics calculator

Pick what each parent carries and see every hatchling the pairing can produce, with the odds for each. Free, no signup, and it covers all 6 proven sugar glider genes.

Sugar gliders are bred on genetics that no one has written down properly. The breeder sites mostly agree, and where they don't this page says so instead of averaging them into a number that looks confident.

What this calculator can and can't tell you

Leucistic, cremeino and albino are recessive — they hide in carriers, so a standard grey glider can be sitting on any of them.
Platinum, mosaic and white face all show on a single copy, so a glider that isn't showing one isn't carrying it.
Ruby Leu is leucistic plus cremeino: the white coat with the garnet eyes. True Platinum Mosaic is platinum plus mosaic. Both are pairings of genes you already have, so pick the parts and the calculator names the result.
The unsettled question is whether platinum and leucistic share a locus. The sources say a platinum can carry leucistic but a leucistic can never carry platinum, which is what you'd see if they did — then call them separate genes anyway. They're crossed here as separate, and that assumption is flagged in the results.
Caramels are a separate closed population rather than a colour, so they're recorded as a lineage. That makes this a pedigree problem more than a genetics one, the same way it is for leachianus.
There is no Morphpedia for this species. Everything here traces to breeder sites, which is the best available and still not the same thing as a reviewed reference.

Platinum is a special case. The sources agree that a platinum can carry leucistic but a leucistic can never carry platinum. That asymmetry is what you'd see if the two sat at the same locus — a leucistic is already using both of its slots there. The same page nonetheless calls them separate genes. They're crossed here as separate loci, matching what the source says rather than what it implies, and the difference shows up in every platinum-to-platinum pairing. It's the first row to settle if you breed them.

Mosaic is a special case. Described as co-dominant and as never heterozygous, which can't both be true. Treated here as showing on one copy. Mosaic patterning is also famously unpredictable in where it lands, so even a correct prediction tells you a joey is mosaic, not what it will look like.

Caramel is a special case. A separate population rather than a morph, kept as a closed line because crosses are reported to have fertility problems. Recorded as a lineage, not crossed as a gene.

Black Beauty is a special case. Described in the source as neither dominant nor recessive, which is how people describe a line-bred look. Listed, not predicted.

Localities

A locality is a place, not a look. It says which wild population a line descends from, and it passes down by pedigree rather than by any gene — which is why it can only be proved with records, and why a crossed line can never be uncrossed.

Traits no calculator can predict

The Pet Glider and petsugargliders.com classes these as polygenic or structural. They're real traits and they set prices, but they don't sit on a single gene, so no Punnett square predicts them. Anything quoting you a percentage for harlequin or flame is guessing.

What does work for these is records: pair the same two animals for a few seasons and your own hatch data tells you far more than any average could. That's what My Reptile Atlas is for.
