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.
Genetic Similarity: We All Have the Same Genes. Each person has the same set of genes - about 20,000 in all. The differences between people come from slight variations in these genes. For example, a person with red hair doesn't have the red hair gene while a person with brown hair has the brown hair gene.. Instead, all people have genes for hair color, and different versions of these genes dictate whether someone will be a redhead or a brunette.
