Samples Accepted: Blood, Hair
Locus Information: E series
Test Information: This test detects both known mutations in the MC1R gene that cause the chestnut color. The chestnut color is autosomal recessive, as an animal must have two copies of the allele to show the color. Animals with only only copy will be carriers for the chestnut color.
