The Barred Chocolate is based on a heterozygous black and bronze base with the brown mutation e, Genotype (Bb ee for males and Bb e- for females).
The most common breeding to make barred chocolates is by crossing a chocolate tom to a bronze hen. Female barred chocolates are produced in the first generation with the males produced being barred blacks that carry brown. Subsequent breedings with the (e) brown gene carrier barred black males to either chocolate or barred chocolate females will then produce some barred chocolate males as well.
When breeding barred chocolates together results are auburn, chocolate and barred chocolate.
