A calculation of the contribution that galaxies in clusters make towards the clustering exhibited by all galaxies is presented. It is shown that, within observational uncertainties, cluster galaxies may be responsible for all the clustering measured by the galaxy-galaxy correlation function (GGCF). This confirms that cluster galaxies make a significant contribution to the two-point fucntion on a scale of 1 h −1 Mpc. This then accounts for the apparent paradox that the two-point correlation function in redshift space is elongated along the line-of-sight on scales where GGCF is significantly less than unity.
