| Phenotype | a/a | A/A or A/a | a/a | A/A or o/a |

| Calico (O/o) | 6a | 13b | 0 | 0 |

Genotypes at the agouti locus (a/a, A/a, or A/A) are represented in columns 2–5, based on the phenotype in the orange fur parts of domestic cats. No cats of orange coat color lacked tabby pattern (columns 4 and 5) and cats with tabby pattern in orange were of both agouti and nonagouti genotype.
a
All 6 individuals homozygous for the agouti deletion (a/a) displayed an absence of pattern in the nonorange fur parts.
b
All 13 individuals carrying at least one wild-type allele (A/A or A/a) displayed tabby pattern in the nonorange fur parts.
