the late sexual maturity in sturgeon and the absence of morphological differences between males and females makes sex discrimination difficult. identification of sex at an early life stage is of high interest in caviar production because it allows efficient selection of females. in this study, the genome of 10 mature male and 10 mature female specimens of persian sturgeon (acipenser persicus...

objective(s):to determine the fetal discernment in suspected cases of sex linked recessive disease in the first trimester of pregnancy. materials and methods: after collection of 100 chorionic villi samples, the dnas were extracted and baby gender was determined. meanwhile, after increasing the sensitivity, the system was able to detect the sex of each cell which was obtained by biopsy. results...

The salmon louse (Lepeophtheirus salmonis (Krøyer, 1837)) is a parasitic copepod that can, if untreated, cause considerable damage to Atlantic salmon (Salmo salar Linnaeus, 1758) and incurs significant costs to the Atlantic salmon mariculture industry. Salmon lice are gonochoristic and normally show sex ratios close to 1:1. While this observation suggests that sex determination in salmon lice i...

Sexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly among species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example has yet been recorded among non-bilaterians. However, the quasi-ubiquitous repartition of GSD among multicellular species suggests that similar evolutionary forces can promote this...

The early bi-potential mammalian gonad requires the expression of a Y-linked gene, Sry, during a brief window of time to ensure proper testis development. WT1 and its direct target gene Sf1 function during sex determination as well as in the specified testes and ovaries. We have previously shown that the transcription co-factor CITED2 interacts with WT1 to stimulate the expression of Sf1 in the...

1. In environmental sex determination (ESD) gender is decided after conception, depending on the environment, rather than being genetically fixed. ESD in plants has been mainly studied in angiosperms, where the dominant form of ESD is sexual lability. Surprisingly, ESD has rarely been studied in homosporous ferns, the only plants in which ESD is the rule, rather than the exception. 2. Here, we ...

We have developed a new method for sex determination based on simultaneous detection of the SRY (sex-determining region Y), STS (steroid sulfatase) and amelogenin (AMELX and AMELY) gene regions and their homologous sequences. The sex of 246 blood samples was correctly determined by this method. An AMELY-deleted male sample, which would have been erroneously considered female based solely on ana...
