  1. The four amino acids at positions under selection in newly generated alleles (underlined) are amino acids found in the parental sequences (white boxes) for A/the het-E gene, and B/the het-R gene. Bolded pairs of amino acids were generated in the mutants. Repeats are named after their positions in the mutated alleles, the class of the corresponding mutant is indicated in brackets.
