WebKey Definitions of Probability in Genetics. The s um law (or sum rule) - To find the probability of two (or more) events occurring, as long as all the events are mutually exclusive (meaning that either one event can happen, or the other can happen, but not both), you must add the probabilities of each individual event occurring together. Five parts of Mendel's discoveries were an important divergence from the common theories at the time and were the prerequisite for the establishment of his rules. 1. Characters are unitary, that is, they are discrete e.g.: purple vs. white, tall vs. dwarf. There is no medium-sized plant or light purple flower.
