1993), indicating coamplification of a minimum of four loci. Assuming identification of individual loci and examination of only selectively neutral (fourfold degenerate) codon positions, rates of substitution must still have been sufficiently high to outpace speciation, if they are to allow discrimination of mbuna interrelationships. At this time it is unknown whether the Mhc system will fulfill all of the necessary criteria. More generally, sequence variation in other portions of the nuclear genome could potentially provide information sufficient for phylogenetic analysis; mutational mechanisms and methods for analysis of DNA sequences are well understood for nuclear genes.
