Hereditary vitality is the organism of two different characteristics, can not be confused. At the same time, these two characteristics are closely linked and influence each other. For example, we all know that plant inbreeding year after year loses its vitality and undergoes very drastic changes in its form, often becoming the abnormally interrelated plant of its various organs.
