Lovebird Genetics

Mutation Guides
Every Fischer's lovebird mutation explained, Opaline, Aqua, Yellow Face, Cinnamon, Violet, Dark Factor and more. Each guide covers inheritance type, visual identification, and the pairings that produce it, backed by the Lovebird Compendium (Dirk Van den Abeele, 2016).
Slaty is autosomal dominant, so it shows with a single copy and no split form exists. Single factor vs double factor, why the slate-grey cast reads strongest on blue series birds, and every cock × hen pairing.
Pale is a proven sex-linked recessive mutation in Fischer's at the sex-linked ino locus, symbol ino-pe, allelic with SL ino and pallid. Roughly 20 percent eumelanin reduction against pallid's 50 percent, red eyes at hatch, and every cock × hen pairing.
Dominant Pied is autosomal dominant, so it shows with a single copy and no split form exists. Single factor vs double factor, how to identify a DF bird, and every cock × hen pairing.
Recessive Pied needs two copies to show and hides completely in a split. Every cock × hen pairing, how it differs from Dominant Pied, and where Mottle fits.
No confirmed red gene exists in Fischer's lovebirds. What psittacofulvin, Opaline spread and diet actually do, plus every cock × hen pairing under the autosomal recessive model the calculator applies.
Pastel is an allele of the NSL ino locus, which is why it forms visual Pastel // Ino and Pastel // DEC compounds. Every cock × hen pairing, plus Pastel vs Dilute vs Pallid.
Sapphire is a blue1-blue2 crossing-over at the blue locus, not a new gene, which is why the calculator deliberately does not model it. What that means for your pairings, sapphire vs parblue, and the current OGVZW research status.
Everything you need to understand Opaline inheritance, sex-linked rules, what splits look like, how to reliably produce Visual Opaline females, and the 5 most important pairings.
Aqua Homo behaves autosomal recessive, while Aqua B1 and Aqua B2 are co-dominant blue-locus compounds. Why the three are not interchangeable, and the exact offspring you get from each Aqua pairing.
Full melanin removal, and why Ino in Fischer's lovebirds is NSL ino, an autosomal recessive at the a-locus shared with DEC and Pastel, not the sex-linked ino of Peach-faced.
Two separate, non-allelic autosomal recessive genes. Both show bright red eyes, so body colour is what tells them apart, and that is why the two should never be combined.
Yellow Face is an allele of the blue locus, so it shares its two slots with Blue, Aqua and Parblue. How YF inherits, how to confirm splits, and the best combinations with Opaline and Aqua.
Why Blue 1 × Blue 2 doesn't produce Blue, it produces Parblue. And how that's completely different from Aqua. All pairings with percentages.
Violet is autosomal incomplete dominant, so no split form exists. SF vs DF, why Violet looks best on a Blue background, and the pairings that produce the deepest violet expression.
Cinnamon is sex-linked recessive, females can't be splits. Auto-sexing trick, all 5 pairing outcomes with sex-specific breakdowns, and combined mutation guide.
One Dark Factor copy = Dark Green or Cobalt. Two copies = Olive or Mauve. The spongy zone mechanism explained, with all six colour forms and pairings.
The rarest fallow, and the most dangerous to breed. Why bronze × bronze = ~100% chick mortality, how to identify it by burgundy eyes, and the safe split strategy.
Dilute is autosomal recessive, both sexes can be splits. One-second ID test vs Pale Fallow, all 4 pairings, and how to combine with Aqua and Opaline.
Every Fischer's lovebird mutation in one place, inheritance type, eye colour, visual ID, and links to the full individual guides. AR, sex-linked, and incomplete dominant all covered.
DEC vs Lutino (it is the dark eyes), how DEC is an allele of the same a-locus as Ino and Pastel, the Green/Blue/Parblue DEC // Ino forms, and every pairing verified against the Compendium.
SF vs DF explained, why Euwing and Misty are autosomal incomplete dominant while Greywing is sex-linked, why there is no "split" for these three, all four engine-verified pairings, and why most calculators model dominant mutations wrong.
Pallid is modelled sex-linked recessive and cuts eumelanin by roughly half, but OGVZW does not yet list it as a formally confirmed mutation in Fischer's. Chicks hatch with red eyes that darken within days. Auto-sexing trick, all 5 pairing outcomes, and how to tell it from Ino and Cinnamon.
Parblue is the Blue 1 // Blue 2 compound, so it can never breed true. What split parblue means, how Blue 1 x Blue 2 makes 100% parblue, all pairing outcomes, and combinations like Creamino.
