Summary of the diverse sex determining systems found in Lake Malawi cichlids. Symbols indicate the sex ratio of each family studied. Filled symbols indicate families genotyped for ma rkers on LG5 and LG7. Blue squares indicate families with a significant association for an XY sex-determining locus on LG7. Pink circles indicate families with a significant association with a ZW sex-determining locus on LG5. The two families of M. pyrsonotus segregating both sex determining loci are indicated by the pink circle containing a small blue square. Grey diamonds indicate the family was genotyped, but no associations were found with either LG5 or LG7. Open diamonds indicate genotyping was not performed, or that statistical association was not possible due to highly skewed sex ratios. The taxonomic relationships of the species are shown in the tree on the left.
