Red Whiteside is an allele at the Ws locus. This mutation appears to be incompletely dominant to wild type.

Description

This mutation is a modifier gene that causes white wing shields, but only on homozygous recessive red pigeons. Heterozygous Ws pigeons have an incompletely white wing shield and are sometimes called "rosewings". Red Whiteside squabs appear self-red until their first moult, when they receive their white feathers.

Inheritance

Red whiteside is an autosomal incomplete dominant mutation. This means that only one parent of either sex needs to carry the mutant gene for it to express in the next generation. Unless it is hidden by another modifier, a pigeon not expressing this trait will not pass it onto its children.
