Rosy-faced Lovebird Colour Genetics

The science of Rosy-faced Lovebird colour genetics deals with the heredity of colour variation in the feathers of the species known as Agapornis roseicollis, commonly known as the 'Rosy-faced Lovebird' or 'Peach-faced Lovebird'.

Rosy-faced Lovebirds have the deepest range of mutations available of all the Agapornis species. Generally speaking, these mutations fall into the genetic categories of dominant, co-dominant, recessive, and X-linked recessive (also called "sex-linked recessive"). While this seems fairly straightforward, it can quickly become confusing when a single specimen has multiple examples of these mutational traits.
