A series of tables is shown below. The animal pedigree numbers are listed in the leftmost column, with the pedigree number of its mother and father in the next two columns to the right. The first three individuals are founders, hence their mothers and fathers are arbitrarily represented with the index 0. Their alleles, in the two rightmost columns are assigned. The gene dropping starts with individual 4. The maternal allele is the first chosen. This allele comes from individual 2. The random toss 'heads' selects the left allele of individual 2, the c allele. These steps are shown in sequence in the series below. These steps need to be repeated 13 additional times to fill in all the missing cells in the table.
