Traut W, Winking H Meiotic chromosomes and stages of sex chromosome evolution in fish: zebrafish, platyfish and guppy. Dmrt1 is necessary for male sexual development in zebrafish. General and Comparative Endocrinology, 87— Table S2. Sex ratios of offspring groups generated by repeated single pair crossings show close correlation.

Therefore, the primary aim of this project was to find out more about the sex determination of this species. They yielded three male-specific sex markers Fig. Eimon P, Ashkenazi A. No drastic change in sex ratio upon environmental effects experienced at the natural surroundings of the species was observed in any of the studies.

Temperature is one of the most commonly studied environmental cues for sex determination. Nuclear androgen receptor regulates testes organization and oocyte maturation in zebrafish. Vincent Mysliwiec, Matthew S. Genetic analysis of zebrafish sex determining pathway Studies to identify genes involved in zebrafish sex determination and differentiation have, until recently, been hampered by lack of methods to obtain genetic mutations.

Below we review the current progress that has been made in this area.

Cell — Red circles indicate pairs producing offspring with female-biased sex ratio, orange diamond labels the pairs with unbiased sex ratio, whereas blue squares indicate pairs producing offspring with male-biased sex ratio. However, in some important cases, the role of a conserved gene in zebrafish has yet to be established.
