Capital letters indicate that the allele is dominant. The alleles are written in their order of dominance.
Please note:
- The genetic model using 3 different loci for the tabby pattern – Mc, Ta, Sp – is a model, which is likely to changes, if newer research results are available.
- Sp is not in the table, because it is a model to express the spotted tabby colour.
- It is a hypothesis that a white medallion, white gloves are the result of another gene (group) than gene S.
