Independent fusions and recent origins of sex chromosomes in the evolution and diversification of glass knife fishes (Eigenmannia).

Heredity - 1 Feb 2011

Henning F, Moysés C B, Calcagnotto D, Meyer A, de Almeida-Toledo L F

Abstract excerpt

The genus Eigenmannia comprises several species groups that display a surprising variety of diploid chromosome numbers and sex-determining systems. In this study, hypotheses regarding phylogenetic relationships and karyotype evolution were investigated using a combination of molecular and cytogenetic methods. Phylogenetic relationships were analyzed for 11 cytotypes based on sequences from five mitochondrial DNA...
