Body size is a sexually antagonistic trait in the shell\u2010brooding cichlid fish\n                    <jats:italic>Lamprologous callipterus<\/jats:italic>\n                    , as \u201cbourgeois\u201d males must be large enough to carry empty snail shells to build nests whereas females must be small enough to fit into shells for breeding. In this species, there is also a second male morph: smaller \u201cdwarf\u201d males employ an alternative reproductive strategy by wriggling past spawning females into shells to fertilize eggs.\n                    <jats:italic>L.\u00a0callipterus<\/jats:italic>\n                    male morphology is passed strictly from father to son, suggesting Y\u2010linkage. However, sex chromosomes had not been previously identified in this species, and the genomic basis of size dimorphism was unknown. Here we used whole\u2010genome sequencing to identify a 2.4\u2010Mb sex\u2010linked region on scaffold_23 with reduced coverage and single nucleotide polymorphism density in both male morphs compared to females. Within this sex region, distinct Y\u2010haplotypes delineate the two male morphs, and candidate genes for body size (GHRHR, a known dwarfism gene) and sex determination (ADCYAP1R1) are in high linkage disequilibrium.
