Mendel found that each individual carries two copies of the allele for each trait and that one copy is passed on to each offspring. When studying the inheritance of two different traits, Mendel found that the patterns of inheritance of one trait do not affect the patterns of inheritance of another trait. This concept is now called independent assortment.
