Recent Activity. Recent publications suggest that environmental factors within the natural range have minimal impact on sex ratios of zebrafish populations. Those individuals with unclear sex were not included in the calculation of sex ratio.
Nucleic Acids Res — In two families, we managed to generate an all-male offspring in the F3 generation Fig.
For the B. We found significant differences in heat response, with the heat-sensitive species adopting a strategy of long survival and low population growth, while the heat-tolerant followed the opposite strategy. In a previous laboratory study, we quantified acute heat response of different clones belonging to B.
Variations on this theme also exist.
Administering estradiol at male-producing temperatures generates females that are physiologically identical to temperature-produced females. The Journal of Experimental Zoology. Ohno, Susumu. The warmth early in the season ensures female-biased broods that then have more time to grow and reach maturity and possibly reproduce before they experience their first winter, thereby increasing fitness of the individual.
For pairwise comparisons the pairwise Wilcox test was used with a Bonferroni correction. Ma, Q. Two separate transcriptome assemblies were created for B. Review of Biology. This suggests that induction of hsp90 gene along with heat might be a common mechanism in aquatic organisms.
Genes encoding for hsp 10, hsp 40, and hsp 60 were differentially expressed only in B.
