|Common name||Web lethal|
|Description||Webbing between toes, typically lethal before hatching.|
Web lethal (symbol wl) is a recessive morphological mutation located at the wl locus.
Homozygous (wl//wl) and hemizygous (wl//•) web lethal pigeons typically die before hatching, and the dead-in-shell baby will have webbed toes. This mutation is unrelated to the mutation at the w locus that can cause a similar webbed foot phenotype.
Web foot - a similar webbed toe phenotype.
