Sex determination
Abstract:
The snakeskin gourami (Trichopodus pectoralis) has a high meat yield and is one of the top five aquaculture freshwater fishes in Thailand. Snakeskin gourami is not externally sexually dimorphic and its sex determination remains unknown. Understanding the sex determination system will contribute towards full-scale commercialization, considerable value to fish farmers for the use of sex-controlled breeding biotechnologies. In this study, a cytogenetic analysis did not reveal any between-sex differences in chromosomal patterns. We use identify male and female linked loci reached the criteria of moderately sex-linked loci (70:30; 80:20; 90:10 and 100;0), indicating that the snakeskin gourami tends to exhibit an XX/XY sex determination system. However, we did not find any male-specific loci after filtering the loci for a ratio of 100:0 ratio of males:females. This suggests that the putative Y chromosome is young and that the sex determination region is cryptic. This approach provides a solid baseline to reveal the sex determination mechanism, allowing further investigation of genetic improvements in snakeskin gourami.
