However, the evolutionary causes of this diversity remain. Sexual reproduction is one of the most highly conserved processes in evolution. Sex-determination mutants Singer, Mary E.

Delbridge M, Graves J. Semin Cell Dev Biol. Therefore, analysis of zebrafish and other fish species utilizing the PGSD system could be important for basic research and potentially useful for aquaculture projects as well.

BMB Rep. Examples of other environmental cues that also have an influence on sex include pH in guppy [19] and social interactions in some reef fishes [20]. Ferguson M, Joanen T. Over the past few decades, there have been conflicting reports on the mode of SD in zebrafish; some of them predicted genetic mechanisms [ 23—26 ], whereas others pointed toward environmental clues [ 2728 ].

Disease Model Mech 3: — Males and females showed differential patterns of changing connectivity in large-scale RSNs during normal aging from early adulthood to late middle-age. Sci Total Environ, 01 Aug

In order to investigate the potential reason for skewed family sex ratios repeated single pair crossing was carried out. This indicates that the underlying genotype of each individual is directing sexual development in response to environmental stimulus.

Rearing density has a limited effect on sex ratios in zebrafish Density has been shown to affect sex ratios in some fish species see [59] for review.
