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.
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.
