| Several authors, observing that 64 is equal not only to 4 but also to 2, suggest organizing the codon table as a six-dimensional hypercube. |
| In Cf genes, there are several instances in which the recombination break point coincides with a hypervariable codon. |
| The proximity of the nonsense mutation to the start codon indicates that these mutations are null alleles. |
| Polar mutations change a sense codon for a specific amino acid within a gene into a nonsense or translational termination codon. |
| In the above simulation, I assumed that for every codon, there were at most two alleles segregating in the population at any given time. |
| For example, M 3,2 is the number of triplet events affecting positions 2 and 3 of one codon and position 1 of the following codon. |
