With allele crossing we can represent it for an easier understanding by a table like the following:
                  _______Parent 1_______
              |    |____a1___|____a2____
              |a3|    a1a3      |      a2a3
Parent 2|__|_________|__________          
              |a3|    a1a3      |      a2a3
              |    |                  |

It is possible to form two genotypes. When the there is one homozygous individual, the variety in the combination will depend solely on the variation of the other parent.
