Look at the chart to the right. Here are two sample Ferilon genes, the genes controlling Mutations.
The f-gene controls the Features possible. The subsequent line of genes, in this case w, x and j (and 0 -- indicating "no" gene), indicates the actual mutation carried.
Each cub will inherit ONE of the f-genes from each parent. The Male gene is "jogged" left gene -- cubs 1 and 3, right gene -- cubs 2 and 4...
While the Female genes are carried this way: left gene -- cubs 1 and 2, right gene -- cubs 3 and 4.
This simply mixes the genes properly for the chart.
According to the gene chart, the F! gene means that NO mutations, even those carried on the other gene, will show up.
Cub 1 here will pass along its father's f gene (along with the W, fey wings) to two of its offspring, and the F! to two others.
Cub 2 will not pass along any mutations, but the F' gene may allow something hidden to show up in its offspring.
