Abstract

A solution is presented for the problem of how to find ancestral codons which minimize the number of mutations over a given network of species for which character-states of aligned amino acid sequences among the contemporary species are known. Three theorems which allow this "maximum parsimony"problem to be solved are proved; then the use of these theorems in finding maximum parsimony ancestral codons is illustrated on a network of chicken and mammalian alpha globin amino acid sequences at two alignment positions.
