This trait is attached to horses that Carry Ether.
Ether is a base coat dilution that causes a silvery-blue to purplish tone throughout the coat.

Ether is recessive; a horse needs to be homozygous with two copies of the gene (erer) for it to be visible.
A carrier with only one copy of the gene (ner or Cher) will not express Ether.

Genotype: ner
Locus:  Not shared with any known genes
Horses with 'ner' or 'Cher' will be noted as 'Carrying Ether' but will not show the gene.

Expression of heterozygous (carried) Ether:

• Coat: Not affected.
• Mane and Tail: Not affected.
• Skin: Not affected.
• Eyes: Not affected.
• Hooves: Not affected.
