Sex chromosome and sex locus characterization in goldfish, Carassius auratus (Linnaeus, 1758).

ABSTRACT:

Background

Goldfish is an important model for various areas of research, including neural development and behavior and a species of significant importance in aquaculture, especially as an ornamental species. It has a male heterogametic (XX/XY) sex determination system that relies on both genetic and environmental factors, with high temperatures being able to produce female-to-male sex reversal. Little, however, is currently known on the molecular basis of genetic sex determination in this important cyprinid model. Here we used sequencing approaches to better characterize sex determination and sex-chromosomes in an experimental strain of goldfish.

Results

Our results confirmed that sex determination in goldfish is a mix of environmental and genetic factors and that its sex de
