N2  - Even after decades of research, the origin of multiple stellar populations in globular clusters (GCs) remains enigmatic. The question as to whether the galaxy environment plays a role in their formation remains unanswered. To that extent, we analysed two classical (>10 Gyr old) Large Magellanic Cloud GCs, NGC 1786 and NGC 1898, using imaging data from Hubble Space Telescope to compare and contrast them with ancient Galactic GCs to assess systematic differences that might exist between their abundance variations. We calculated their red giant branch width, subtracted the effect of metallicity, and compared it with the available data on Galactic GCs by plotting them against initial and current cluster mass. We see that the two clusters follow the same general trend as that of the Galactic GCs, and Galactic GCs from different progenitors follow the same general trend as one another, indicating that the galaxy environment may only play a minor role in the formation of multiple stellar populations within GCs.
