Note 1: Non-Agouti kittens may be be born with Tabby Markings which disappear with maturity.
Note 2: Phaeomelanin does not effectively mask Tabby Patterns so that a non-Agouti Red may be indistinguishable from an Agouti Red.

SPOTTED TABBY

Dominant Spotted gene (or group of genes) breaks up non-ticked Tabby Patterns. See example below.
