转一段CFA上关于折耳尾巴的问题的文章
Originally, many Folds had foreshortened tails which were inflexible. Dr. Rosemond Peltz, who served as the first genetic consultant for the American Scottish Fold breeders, offered the opinion that "in generations to come the undesirable defect may be diminished by extremely careful breeding." With the knowledge from the Jackson study, breeders began to use more outcrossing and the gene pool increased. This produced longer, more flexible tails and the bone lesions and foreshortened tails began to disappear. In January 1976 the stud book closed to all outcrosses except the American Shorthair and the British Shorthair.
Today outcrossing remains a fundamental part of Scottish Fold breeding programs. Without the help and generosity of American and British Shorthair breeders who share their beautiful cats with Fold breeders, this breed might well be lost to the cat fancy and all those who love the "Foldie." More points are placed on the tail of the Fold than in any other breed's standard. Our standard reads that the tail must be flexible, with long and tapering preferred. One of the first questions a prospective owner should ask a breeder is "is the tail flexible?" Careful breeding practices, Fold Ears (Fd) to Straight Ears (fd) or to an allowed outcross, virtually eliminates the stiff tail. It is believed that the gene which causes folding of the ears is an incomplete dominant. From the time of the first study done by Oliphant Jackson, Ph.D., the mandate to breed only Fd to fd or outcrosses has been strongly stressed, and this remains true today.
With the problems arising from the GCCF ban and Dr. Jackson's study in 1975, the Scottish Fold breeding program was rapidly declining in England. Mary Ross sent a plea to ISFA (International Scottish Fold Association) saying only one other cat lover beside herself was actually breeding them. Folds were in danger of being lost in England and Mrs. Ross asked for help from breeders in the United States. The response was quick and in the late 1970s, several people took up the cause of the Folds. Jean Grimm (Furrytails), Lois and Clark Jensen (Jensen), Pat Dreifuss (Beachmor), Shirley Norquist (Kangaroo), to name a few, started working on breeding programs.
In May 1977 Scottish Folds were given provisional status in CFA. A look at those early pedigrees shows that several breeds were originally used to increase the gene pool and return the cats to their original barn cat "hale and hearty" state. The Scottish Folds of today lead long, healthy lives, often up to and past the age of 19 years, and several Folds have been active in the ring over the age of ten. The popular misconception that Folds become crippled as they age is just that - a misconception. The year 1978 was a banner year for Folds - they received Championship status! Jensen Minnie Pearl became the first Scottish Fold Grand Champion in 1979. "Minnie" was the first Scottish Fold to make it into the top 20 and was, of course, also the first Best of Breed. |
