Only two possible alternative genes can occupy a given location (locus) at any give instance. The production of sex-cells (called meiosis) separate all "paired" genes; therefore, it creates an opportunity for the inclusion of an alternative gene upon chance fertilization in the next generation. In the chart below the genetic make-up (called genotype) of "all" the New Types differ from either Parent. Also, notice that there are three (3) alternatives, e.g., C = checker, + = wildtype, and c = barless; and that only two (2) alternatives (called alleles) occur in each of the New Types at fertilization.
