Mutation type Colour modifier

Dilute is an allele at the d locus. This mutation is sex linked and recessive to wild type.


Dilute generally lightens the pigment intensity of the feathers, changing blue to dunn, brown to khaki, and ash red to yellow. Dilute pigeons also have short down in the nest.


Dilute is a sex-linked recessive mutation. This means that both parents need to carry the mutant gene for it to express in a cock the next generation, but only the father needs to carry it for the gene to express in a hen. As a sex-linked recessive mutation, it is possible for this mutation to be carried by cock bird who does not visually express it, but any hen who carries the gene will show it.


Apart from wild type, the other alleles at the d locus are pale and extreme dilute.


Dilute is part of a number of phenotypes, including yellow, silver, dunn, and khaki.
