![]() ![]() ![]() This kitten was registered as a silver ticked tabby in 1996 before CFA declared that no ASH ticked tabbies were registerable in the breed. The dam of the kitten in Figure 1b is CH Solmer Ophelia of Stedam, a gold-eyed white masking brown-patched tabby. The dam of the kitten in Figure 1a was a shaded cameo female (CH, PR Melodygarden Tidy Tips) and this is a kitten picture of GC Melodygarden Northern Lights, CFA's first grand champion shaded tortoiseshell ASH. The sire of both kittens is a purebred shaded silver male: GC, GP Melodygarden Stargazer. Neither is the outcross of another breed. These half-sisters were born 2 weeks apart. In Figures 1a and 1b, are two female kittens about 4 months old. There had been much controversy concerning the genetics of unpatterned tabbies in the American Shorthair (ASH) breed. Your question is of sufficient depth that a decent explanation would need come from a geneticist who's been involved specifically with the study of these particular loci, and their interaction, which narrows the field considerably.The Genetics of Shaded Silver American Shorthairs Genetics of the shaded American Shorthair The particular interaction between the modifier alleles and the Melanin Inhibitor, Agouti and Banding mutations falls at the extreme outside edge of our understanding at present (my own knowledge stops roughly at the spelling of the word "cat"). Les Lyons is in the midst of a long term study of Silvers (and Goldens) which will ultimately answer the whole question ( doubtless - she's absolutely tenacious), and the research call may be found here: Silver and Golden Chinchilla Persians, which show the effects of WB and silver). Simple Truth: we don't yet know enough about the interaction of Wide Band and Polys to even comprehend how the complex values render themselves, though we know the extremes of Wide Banding, since breeders have been "accidentally" using this as a focus in certain cats (e.g. a badly expressed or weak "a" or an overexpressive "I" will perform almost as the Dilution allele does, yielding a washed-out Smoke or Cameo). The expressive value of the modifier or modifiers (predicted) gives various Smoke and Cameo coats (e.g. Paw pads: black.Įye color: green, hazel, or brilliant copper.Īll Tabbies are either AA or Aa, and the Inhibitor allele - I/i - produces hairs which are either white at the base (the dominant: I), or (with the recessive: i) self-coloured at the base.

In the photo below the litter of kittens is less than 24 hours old. Generally, my silver kittens tabby markings faded within a couple of weeks from birth, whereas the goldens take longer. Most silvers (and goldens) are born with some tabby markings, but they fade. ![]() While it isn't a great photo I hope you can see the mantle of tipping on his back. ![]()
