Researchers have found that there are 6 genotypes of the hepatitis C virus and they all may respond differently to treatment. Careful screening of the patient and identification of the genotype is necessary before starting the treatment in order to determine the most effective treatment for the patient. Approximately 15% to 25% of people who are infected with hepatitis

protein M‚ envelope protein E; seven nonstructural proteins‚ NS1‚ NS2a‚ NS2b‚ NS3‚ NS4a‚ NS4b‚ NS5; and short non-coding regions on both the 5’ and 3’ ends. Based on the analysis of the envelope protein there are at least four genotypes (1 to 4) - The American African genotype has been estimated to have evolved between 1907 to 1949. This period includes World War I and II which were associated with considerable movement of populations and environmental disturbance‚ factors known to promote the evolution

Chapter 9: Patterns of Inheritance What pattern will inheritance follow? Why is it important? Always follow patterns? Rule of Probability In tossing a coin the odds of either a head or tail is always 50%. The outcome is unaffected by the previous attempt. If 2 coins are tossed‚ each will be dependent of the other HH‚ HT‚ TH‚ TT (Probability is 25% or ¼) The rules also hold true for genetics due to the law of independent assortment. Each alternative type of outcome in a gene acts independently
