Slaty Lovebird Genetics: SF, DF and All Pairings
Slaty 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 Lovebird Genetics: Sex-Linked Inheritance, Red Eyes at Hatch and All Pairings
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 15 percent eumelanin reduction vs pallid's 50 percent, red eyes at hatch, and every cock × hen pairing.
Dominant Pied Lovebird Genetics: SF, DF and All Pairings
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 Lovebird Genetics: Inheritance, Splits and All Pairings
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.
Red Factor Lovebird Genetics: What Is Actually Confirmed, and What Is Not
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 Lovebird Genetics: Inheritance, Ino Compounds and All Pairings
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.
Turquoise in Lovebirds: What the Current List Actually Records
OGVZW’s 17 August 2025 list does not record turquoise in Fischer’s lovebirds. The bird sold as turquoise is the parblue compound bl1 // bl2.
The White Eye-Ring Group: Fischer’s, Masked, Nyasa and Black-Cheeked
The four Agapornis eye-ring species compared: rings, ranges, visual markers and where each mutation actually originated.
Sapphire in Lovebirds: Why It Is Not a Separate Mutation
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.
Best Lovebird Genetics Calculator 2026: Free Tools Compared
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.
Complete Lovebird Genetics Guide: All Mutations and Inheritance Rules
The single master guide to Fischer's lovebird genetics, every mutation group, the four inheritance types, and links to all individual mutation guides.
Lovebird Color Breeding Chart: Complete Visual Reference
A complete visual reference, every base colour and mutation, inheritance markers, and quick pairing-outcome tables to bookmark and reuse.
Aqua Lovebird Genetics: B1, B2, and Homo Explained
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.
Lutino Lovebird & Albino Lovebird: Ino Genetics Decoded
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.
What Is a "Split" Lovebird? Explained Simply
The one concept every breeder must understand before planning any pairing, and how to read splits in the calculator results.
Pale Fallow vs Dun Fallow: How to Tell Them Apart
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.
Sex-Linked Mutations in Lovebirds: Males vs Females
Why Opaline, Cinnamon, and Pale behave differently depending on sex, and what "split" means for males but not for females.
Yellow Face Lovebird Genetics: Inheritance, Splits & Best Pairings
Yellow Face is the orange-face gene on its own autosomal-recessive locus, so it stacks with Blue, Aqua and Parblue rather than competing for the blue locus. How YF inherits, how to confirm splits, and the best combinations with Opaline and Aqua.
How to Breed the Rarest Lovebird Mutations
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.
Lovebird Pairing Outcomes: Every Aqua and Blue Cross
Engine-verified offspring percentages for every Aqua and Blue series pairing. Each cross links straight into the calculator.
Blue Lovebird Genetics: Blue 1, Blue 2 and Parblue Explained
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 Lovebird Mutation: SF, DF and Best Pairings Explained
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 Lovebird Genetics: Sex-Linked Inheritance & All Pairings
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 Lovebird Genetics: Sex-Linked Inheritance & All Pairings
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.
Dark Factor Lovebird Genetics: Dark Green, Olive, Cobalt & Mauve
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.
Bronze Fallow Lovebird Genetics: Genotype, Danger Pairings & Breeding Guide
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.
Dark Eyed Clear (DEC) & Decino Mutation in Lovebirds
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.
Euwing Lovebird vs Greywing vs Misty: The Dominant Mutations Compared
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 Mutation in Lovebirds: Split Parblue, Pairings & How to Breed It
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 Lovebird Genetics: Pairing Outcomes, Visual ID & Combinations
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.
Opaline Lovebird Genetics: The Complete Breeder's Guide
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.
