Document Summary
1/24/2017: (a) syringomyelia ( commonly referred to as sm) is a neurological condition in which fluid accumulates in the spinal cord, forming cavities called syrinxes. The effects of the disease includes a weakness of muscles. (b) dermoid sinus is a disease in which incomplete separation of the skin and nervous system occurred during the early parts of life. It is most common in rhodesian ridgebacks. (c) the film discusses many different forms of diseases among different breeds of purebred dogs. Prof. steve jones points out that inbreeding is dangerously done. Additionally, in the film watched in class, they discuss the mating of a female dog being bred with her grandfather. This close of incest leads to an increase in probability of genetic diseases among the offspring: (a) the pedigree german shepherd compared to the working dog, has saggy or limp hind legs and an arched back. English bulldogs now have shorter top jaws with a large underbite.
