1 Introduction Metamorphosis, the discrete morphological change between postembryonic life stages, is widespread across the animal kingdom (Werner 1988; Truman 2019). Adaptive explanations (Table 1) treat metamorphosis as a means of niche shift (e.g., diet and habitat) or fitness-role shift (e.g., feeding, dispersal and reproduction) that decouples early and late life stages (Istock 1967; Ebenman 1992; Moran 1994; ten Brink, de Roos, and Dieckmann 2019).

AbstractSex chromosomes differ from autosomes in both their ploidy and transmission genetics. Consequently, selection, mutation, and drift may act differently upon them, driving distinct patterns in genetic divergence, diversity, and gene content. Recently, researchers have begun to consider a wider set of organisms with non-standard inheritance and sex-determination systems, however in many cases we lack theory which extends to such cases.
