The proposal that radio galaxies in clusters are significantly redshifted with respect to the mean cluster velocities is analyzed, as is the possible dependence of redshift on the morphological type of galaxies in clusters. In the investigation, a nonorthogonal method of two-way variance analysis is used. It is found that the two effects are not independent; the redshift difference between radio-spirals and radio ellipticals is particularly important. The type effect in the Virgo cluster is reanalyzed using an extended complete sample and the type subdivision introduced by Jaakkola and Moles (1976). For 17 clusters and groups, a significant effect with type at 4.2 sigma is found. It is also shown that, when they are of small amplitude, some of these effects could well be a consequence of a different spatial distribution for different galaxy populations, tied to a larger space extension of clusters than usually thought.
