Установлено точное наследование риджа Опции

We have just learned that the specific genetic mutation responsible for the ridge in the Rhodesian Ridgeback has been found.

The work was done by Dr. Leif Andersson at Uppsala University in Sweden in collaboration with researchers at the Broad Institute/MIT here in the U.S. and the Swedish University of Agricultural Sciences. A paper will be published in the coming months, and Dr. Andersson expects a genetic marker test to be available in the fall, pending licensure, etc.

That is all the information Dr. Andersson has given us, along with his permission to disclose it to the Ridgeback community. We know you are as thrilled as we are.

As many of you know, Dr. Mark Neff, in collaboration with RRCUS, was also searching in parallel for the same marker. While Dr. Neff's efforts were not responsible for this discovery, we all agree it is wonderful for the breed.

We are sure this will be a subject of intense interest at Dr. Bell's seminar next Wednesday at the National Specialty in Ohio, as he will be discussing the implications of a direct-marker test for breeders.

Коротко:
Сотрудничество шведов и американцев привело к тому, что 23 мая на семинаре в Америке на Национальной выставке в Охайо будет объявлено о точном наследовании риджа и маркеровочных тестах. способных определить носителей. И т.д.

Upon comparison of the same DNA stretch between the breeds, it was found that the real culprits for the prevalence of dermoid sinus in the dogs were the extra copies of four genes involved in foetal development.

The researchers have revealed that dogs lacking the duplication of genes are unridged, while the ones with one copy have normal ridge.

They also say that having two copies also carries an 80 per cent risk of dermoid sinus.

.... И все-таки ученые обосновывают то, что RR (гомозиготные по доминантному аллельному гену, отвечающему за наследование риджа) подвержены риску заболевания ДС более, чем остальные собратья (Rr, rr)...
