Lovebird Genetics

Genetics Basics
Start here if you are new to lovebird genetics. These guides explain the core ideas every breeder needs, what a split is, how sex-linked inheritance works, hen genetics, and how Fischer's lovebird colours come together.
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.
The one concept every breeder must understand before planning any pairing, and how to read splits in the calculator results.
Why Opaline, Cinnamon and Pale behave differently depending on sex, and what "split" means for males but not for females. Pallid is reported but not yet formally confirmed in Fischer's, and Ino here is autosomal recessive, so it does not belong in this group.
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.
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.
