We analyze the structural parameters and stellar population characteristics of early types in the Virgo cluster. In both cases, we find noticeable deviations from a simple joint behavior of dwarfs and giants; nevertheless, by comparison to a semianalytic model of galaxy formation, we conclude the relations might be reproduced by processes that form dwarfs and giants altogether. The work presented here is based on Janz & Lisker (2008, 2009).
