A dense linkage map of Lake Victoria cichlids improved the Pundamilia genome assembly and revealed a major QTL for sex-determination
July 11, 2018
This high-resolution linkage map was used to anchor the scaffolds of the Pundamilia genome and estimate recombination rates along the genome. Via QTL mapping, we identified a large locus for sex determination in a ~1.9 Mb region on Pun-LG10, which is homologous to that of Oreochromis niloticus LG 23 (Ore-LG23) and which contains a gene (amh) known to be responsible for sex determination in several vertebrate species.
