This trait is attached to horses that Carry Pearl.
Pearl is a base coat dilution that causes a shiny warm saturated brown color throughout the coat.

Pearl is recessive; a horse needs to be homozygous with two copies of the gene (prlprl) for it to be visible.
A carrier with only one copy of the gene (nprl) will not express Pearl.

Genotype: nprl
Locus:  Shared with Cr and Tp; horses with 'Crprl' are Cream Pearl. Horses with 'Tpprl' are Tapestry Pearl.
Horses with 'nprl' will be noted as 'Carrying Pearl' but will not show the gene.

Expression of heterozygous (carried) Pearl:

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