The dorsal hair ridge in Rhodesian and Thai Ridgeback dogs is caused by a dominant mutation that also predisposes to the congenital developmental disorder dermoid sinus. Here we show that the causative mutation is a 133-kb duplication involving three fibroblast growth factor (FGF) genes.
1 sty 2007 · It was shown that the dorsal hair ridge in ridgeback dogs is caused by a 133 kb duplication of three fibroblast growth factor genes FGF3, FGF4 and FGF19 and the ORAOV1 gene. Dogs homozygous for...
The short answer is: Probably not. Many people who have never seen a Ridgeback confuse a dog’s “hackles” – the hair standing up on the shoulders and sometimes the back, often when the dog is excited – with a ridge. (The technical term for this is the vaguely naughty sounding “piloerection.”)
28 mar 2022 · Taking the initiative to map the hair ridge trait in Rhodesian Ridgebacks, scientists identified a segment of DNA that was found in Ridgebacks and the analysis revealed the precise genetic cause of ridges in this awesome African dog.
A study of Rhodesian Ridgeback dogs indicates that the duplication responsible for hair ridge is not identical with the hypothesized locus for dermoid sinus. Anim Genet. 2022 Apr;53 (2):231-233. doi: 10.1111/age.13172. Epub 2022 Jan 23. Authors. Xuying Zhang 1 , Ottmar Distl 1. Affiliation.
12 lip 2023 · Here’s the answer: The famous “ridge” in Rhodesian ridgebacks is caused by a genetic mutation. This mutation is responsible for causing duplicate copies of three growth factor genes. The excess copies of these three genes result in the stripe of backward growing hair on a ridgeback.
