When symptoms are present, diagnosing the presence of osteophytes is a combination of a clinical exam of the joints and x-rays. Once the presence of osteophytes is confirmed, the treatment will depend on the severity of the disease.
While the genetic difference between individual humans today is minuscule â about 0.1%, on average â study of the same aspects of the chimpanzee genome indicates a difference of about 1.2%. The bonobo (Pan paniscus), which is the close cousin of chimpanzees (Pan troglodytes), differs from humans to the same degree.
Humans have in common 99.7 percent of their genes, but the remaining 0.3 percent is responsible for differences between people. Humans have between 20,000 and 25,000 genes. Genetic mapping provides answers about patterns of inheritance in individuals and groups of organisms. Physical traits or inherited disorders often cluster in families and are the result of a combination of genetic and environmental factors.
