A method based no SRY gene for controlling the mammal to reproduce female ones features that the nucleic acid vaccine or protein vaccine using SRY protein as target antigen is used to immunize the female mammal for inducing specific immune reaction to SRY protein. The immune system in mother ...
because the father of the sporadic XY female that bears it has the normal sequence at the corresponding position. These results provide strong evidence for SRY being TDF. About this article Cite this article et al.A human XY female with a frame shift mutation in the candidate testis-determining...
During the embryonic stage, the fetus begins with undifferentiated gonads, which later develop into either testes or ovaries. The presence of theSRYgene influences the gonads to develop into testes. In the absence of this gene, the gonads default to becoming ovaries. The ovaries are ...
The main categories begin with the sex chromosome complement. Disorders are therefore either sex chromosome, XX, or XY DSD. The presence of the SRY gene is listed next. The gonadal type (ovary, testis, ovotestis, or dysgenesis) follows. The tubular genitalia and the external appearance are lis...

As male grasshoppers carry only a single X, the lack of a pair leads to two distinct gametes. Each carries either an X or no sex chromosome at all. At the same time, all female gametes are of the X type. Thus, fertilization by the male gamete with an X or no sex chromosome det...
In the male, the SRY (sex-determining region Y) gene on the Y chromosome directs development of the sex cords into seminiferous tubules with Sertoli cells surrounding the centrally placed germ cells (prospermatogonia). Leydig (interstitial) cells are derived from somatic progenitor cells within the...
The notion that Polycomb regulates the female gene regulatory network has been supported by other recent evidence. In bipotential precursor cells, genes involved in sex determination are marked with bivalent chromatin domains [19] that are prevalent in pluripotent stem cells and in germ cells [55,...
If this gene is active, it makes testes develop instead. This switch is seen as the key event in determining whether a baby is a girl or a boy. Only after the gonads(性腺) form and flood the body with the appropriate hormones, the theory goes, is the sex of our minds and bodies ...
