French Bulldog DNA Color Charts
The French Bulldog DNA color chart is the ultimate guide to understanding a Frenchie’s genetic traits. The chart includes specific loci, such as E, K, A, B, D, S, M, and Coco, and analyzing them can help you predict a French Bulldog’s coat color and pattern. This blog is all you need to understand the DNA color chart. Keep reading to find out more!

The E Locus has the following combinations of genes:
1. Em / Em: This combination means that your Frenchie will have a masked appearance.
2. Em / E: The bulldog will have a masked appearance.
3. Em / e: Also a masked appearance combination.
4. E / E: This means that the dog will not have a mask but might carry the cream gene.
5. E / e: No mask but might carry the cream gene.
6. e / e: The dog will have a solid cream color and will hide other colorings (K Locus and A Locus)

The K Locus Frenchie DNA color chart has three possible combinations. However, if your dog has the e e genes, then they will override all K Locus results.
1. Kbr / Kbr: Will have brindle color.
2. Kbr / Ky: This also means that the dog will have a brindle color.
3. Ky / Ky: The dog will display a fawn color.

The A Locus has multiple combinations. Similar to K Locus, if your French Bulldog has the e e genes, they will overrule all A Locus results.
1. Ay / Ay: The dog will display fawn color.
2. Ay / Aw: Fawn or sable color.
3. Ay / At: Fawn or sable color and might carry tan points genes.
4. Ay / a: Will have fawn or sable color and may also carry recessive black genes.
5. Aw / Aw: Wild sable or agouti color.
6. Aw / At: Wild sable or agouti color but can carry tan points.
7. Aw / a: The dog will have either wild sable or agouti coloring and also carry recessive black.
8. At / At: Tan points or black and tan coloring, and covers the brindle gene.
9. At / a: Tan points or black and tan coloring. Carries recessive black.
10. a / a: The Frenchie will have a solid black color and cover the brindle gene.

The B locus Frenchie DNA chart determines the chocolate coloring of your dog. The possible combinations are:
1. B / B: Not a chocolate color.
2. B / b: Not chocolate but carries the chocolate gene.

The Coco chart explains whether your French Bulldog DNA has chocolate coloring and is considered ‘testable.’ The possible combinations are:
1. Co/Co: The bulldog will not display chocolate coloring.
2. Co/co: This is considered testable but is not chocolate color. However, it carries the chocolate gene.
3. co/co: The dog will have a chocolate color.
