PRINCIPLE OF BLOOD GROUP INHERITANCE AND CALCULATION OF ITS RATIO

This paper shows the principle of blood group inheritance and gives the calculation of its ration based on the law of genetic inheritance of paper. Besides, reason of atavism has been also provided, which is valuable for the research on genetics. Author in this paper think Principle of blood group inheritance and calculation of its ratio improve the non- systematicness and uncertainty. Simple and feasible calculation methods of disease rate are provided for diseases of autosomal dominant (AD), autosomal recessive (AR), X- linked dominant inheritance (XR) and Y- linked inheritance, which is valuable for the research on the genetics in future.
