Fig. 6.

Sex chromosome turnovers in basal haplochromine cichlids in the context of adjacent groups. Topology is derived from Ronco et al. (2021) and Astudillo et al. (2023), with species not included in these studies incorporated according to their phylogenetic position and relative divergence times in other studies (Koblmüller, Schliewen, et al. 2008; Irisarri et al. 2018; Meier et al. 2019; Schedel et al. 2019). Blue indicates an XY system, red indicates a ZW system, and purple indicates the presence of both XY and ZW signal on the same chromosome.
