The origin of the CMR in Virgo
We study the origin of the colour magnitude relation (CMR) in the Virgo cluster. The CMR could be either caused by a variation of the mean stellar metallicity along the sequence (Kodama and Arimoto, 1997) or by a combination of age and metallicity variations (Ferreras, Charlot and Silk, 1999). This uncertainty is due to the fact that the integrated
