Abstract
Globular clusters with composite color-magnitude diagrams, such as NGC 1851, NGC 2808, and Fornax 3, might have formed by mergers. It is suggested that each of these objects had two parent clusters, one with a red horizontal branch and another with a blue horizontal branch. Such mergers could have occurred if both ancestral objects were originally members of a single dwarf spheroidal galaxy in which the internal velocity dispersion was low.Keywords
