![]() ![]() "Ticked" tabby ASH were originally accepted as AOV, but later declared a disqualifier in 1993. Non-silver shaded ASH (such as shaded golden) are currently not recognized for championship. Cameo and shell cameo shaded ASH were accepted for championship in 1971 and in 1993, other colors including shaded blue, cream, tortoiseshell, dilute tortoiseshell and their chinchilla/shell counterparts were accepted. In 1913, a shaded chinchilla female was accepted for CFA registration as a "Domestic Shorthair", a breed designation that later gave rise to both American and British Shorthairs The first silver shaded ASH competed for championship in 1951. The shaded silver is one of the oldest ASH colors. ![]() The history of the shaded ASH has been more extensively reviewed elsewhere. Because the genetics are similar in other breeds and hopefully the readers will find the information useful regardless of breed or color.īefore diving into the genetics, a short history of the shaded ASH pattern is helpful. This manuscript is meant to provide the readership with information about to the genetic inheritance of the shaded pattern and to show the relationship of shaded and unpatterned tabbies with stripes. Although written from experience with shaded American Shorthairs, the genetics are applicable to other breeds and many of the same genes work in nonshaded patterns, such as the classic tabby pattern. It not based on theoretical of "how it is thought to be or ought to be" but rather "how it is." The same genetics have been consistent with 6 lines of shaded cats crossed with classic tabbies from several different lines. The purpose of this article is to describe the genetics that make up the shaded ASH pattern based on actual breedings. Kittens of this coloration naturally arise when a clear shaded cat, regardless of lineage or color is crossed with a classic tabby or a solid masking classic tabby.įigure 1 - These kittens share the same sire, a shaded American Shorthair. 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.
