Her, a gene required for sexual differentiation in Drosophilaencodes a zinc finger protein with characteristics of ZFY-like proteins and is expressed independently of the sex determination hierarchy. The primary goal in reviewing the results to date that span several taxa will be to determine whether Sry is required for brain sexual differentiation in most therian species and potential other genes that might compensate in Sry -deficient species.
Meiosis: the chromosomal foundation of reproduction. BMC Genomics 1291 Sandler L, Novitski E. In the middle pachytene, Y achieved a complete synapsis with X and quickly underwent early complete desynapsis during the late pachytene-early diplotene [ Epigenetic regulation of male fate commitment from an initially bipotential system.
Chromosomal diversity and phylogenetic inferences concerning thrips Insecta, Thysanoptera in a semi-arid region of Brazil. The large size and low number of chromosomes have made Orthoptera an important group for our general understanding of chromosome biology and cytogenetics.
The functional differences were demonstrated for male and female XX chromosomes of E.
Unlike most other taxa, sexualization in fish is exceptionally plastic, which may confer an evolutionary advantage in rapidly changing environmental conditions Todd et al. Steroid hormones at both periods may trigger epigenetic changes in various brain regions that underpin sex differences in brain responses Tsai et al.
Circular transcripts of the testis-determining gene Sry in adult mouse testis. While the proportional contribution of each splice variant to the total mRNA for a given gene might be low, such variants might demonstrate different potencies in binding and activating various cellular pathways.
Transcriptome analyses revealed that different sox genes show stage-specific and sex-dependent expression patterns during gonadal development. An integrative data analysis platform for gene set analysis and knowledge discovery in a data warehouse framework. Epigenetics in alternative pre-mRNA splicing.
The gene wt1a appears to act as an upstream regulator of dmy. In males of this species, evidence suggests that wt1a upregulates dmy , which increases gsdf and sox9a2 but suppresses the expression of rspo1 Nanda et al. Cell Rep. Conflict of interest statement The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
