             abstract = "We present an upgraded version of the MOCCA code for the study of 
                         dynamical evolution of globular clusters (GCs) and its first 
                         application to the study of evolution of multiple stellar 
                         populations. We explore initial conditions spanning different 
                         structural parameters for the first (FG) and second generation of 
                         stars (SG) and we analyse their effect on the binary dynamics and 
                         survival. Here, we focus on the number ratio of FG and SG 
                         binaries, their spatial variation, and the way their abundances 
                         are affected by various cluster initial properties. We find that 
                         present-day SG stars are more abundant in clusters that were 
                         initially tidally filling. Conversely, FG stars stay more abundant 
                         in clusters that were initially tidally underfilling. We find that 
                         the ratio between binary fractions is not affected by the way we 
                         calculate these fractions [e.g. only main-sequence binaries (MS) 
                         or observational binaries, i.e. MS stars >0.4 M-circle dot mass 
                         ratios >0.5]. This implies that the MS stars themselves are a very 
                         good proxy for probing entire populations of FG and SG. We also 
                         discuss how it relates to the observations of Milky Way GCs. We 
                         show that MOCCA models are able to reproduce the observed range of 
                         SG fractions for Milky Way GCs for which we know these fractions. 
                         We show how the SG fractions depend on the initial conditions and 
                         provide some constraints for the initial conditions to have more 
                         numerous FG or SG stars at the Hubble time.",
