Lovebird Genetics Blog, 38 guides
Mutation guides, pairing breakdowns, and genetics explained, built for breeders in Bangladesh, Pakistan, Indonesia, and worldwide. Every article is backed by the Lovebird Compendium (Dirk Van den Abeele, 2016).
New to the calculator? This guide walks you through every step, selecting each parent's mutations, reading sex-linked male/female results, understanding splits, and turning percentages into real pairing decisions.
Read the full guideSlaty shows with a single copy, so 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 mutation in Fischer's at the sex-linked ino locus, symbol ino-pe, allelic with SL ino and pallid. Roughly 20 percent eumelanin reduction vs pallid's 50 percent, red eyes at hatch, and every cock × hen pairing.
Dominant Pied shows with a single copy, so 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 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, not a new gene. What that means for your pairings, sapphire vs parblue, and the current OGVZW research status.
An honest 2026 comparison of the free lovebird genetics calculators, gencalc.com versus this tool, with features, mutations, and which to use for Fischer's.
The single master guide to Fischer's lovebird genetics, every mutation group, the three inheritance types, and links to all individual mutation guides.
Hen-specific inheritance. Why female lovebirds cannot be split for sex-linked mutations, the ZW chromosome rules, and auto-sex pairings.
A complete visual reference, every base colour and mutation, inheritance markers, and quick pairing-outcome tables to bookmark and reuse.
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.
One of the most sought-after pairings in the hobby. Step-by-step genetics with every offspring, percentage, and what to expect visually.
The one concept every breeder must understand before planning any pairing, and how to read splits in the calculator results.
Two separate, non-allelic recessive genes, with different eye colours: Pale Fallow bright clear red, Dun Fallow bright red. Here is exactly how breeders distinguish the two, and why it matters for pairing.
Why Opaline, Cinnamon, and Pale behave differently depending on sex, and what "split" means for males but not for females.
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.
Engine-verified routes to the rarest Aqua and Parblue YellowFace combinations, from the birds you already own up to Aqua Homo YellowFace Dun Fallow, the bird almost nobody has bred.
Every Aqua lovebird pairing and combination with engine-verified results, the Green series, and how to produce 100% Aqua chicks.
Engine-verified offspring percentages for every Aqua and Blue series pairing. Each cross links straight into the calculator.
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 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.
Pallid is modelled sex-linked recessive and cuts eumelanin by roughly half. 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.
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.
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 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.
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.
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.
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 with exact percentages.
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.
How Fischer's lovebird colours actually work, eumelanin vs psittacine pigments, the three inheritance types (AR, sex-linked, incomplete dominant), and how to read a genetics outcome.
Five proven Opaline pairings with exact percentages, how to verify split males, and how to combine Opaline with Aqua, Yellow Face, Pale Fallow, and Ino using the calculator.
A healthy pair lays 4 to 6 eggs per clutch and 2 to 3 rested clutches a year. The full egg-to-fledge timeline, safe limits, incubation, candling, and laying without a mate.
The complete Fischer's lovebird breeding guide, cage setup, rotation method, mutation combination planning, candling, chick rearing, and the record-keeping system used at KinBird Aviary.
