Genetic identification Smoky black

genetically, smoky blacks black horses heterozygous cream gene. mutation produces cream colors on matp gene on equine chromosome 21 (eca21), , incomplete dominant trait. incomplete dominant traits differ recessive traits, visible in homozygous state, , simple dominant traits, visible in homozygous or heterozygous state. instead, matp mutation visible heterozygous state, more in homozygous state. difficulty in identifying smoky blacks has led describe black masking cream, smoky blacks more termed cryptic creams.

the location of cream gene published in 2003 , there exists dna test cream gene. test enables breeders identify cryptic creams such smoky blacks, dark palominos , buckskins, , creams coats obscured action of gray gene or pattern genes such pinto.
