Numbers of Nonsynonymous and Nonsynonymous Substitutions and Rearrangements in wUni and wVitA Based on Comparisons to the Predicted Ancestral Sequence

	Non-Syn (NS)	Syn(S)	Rearrangements(R)	Duplication	Tri.	Quad.
wVitA	24	22	14	32	23	2
wUni	233	128	37	31	5	0

Note.—The numbers of NS and S and R are significantly higher in wUni, whereas proportions of NS to S are not significantly different and proportions of R relative to NS and S are significantly higher in wVitA (see text). Also, both wVitA and wUni genomes contain a large number of duplicated genes. Paralogous genes in each genome were identified by a BLASTp search against the resident genome. A large number of duplications, triplications, and quadruplications of genes were identified in this manner.
