An alternative that has already been successfully tested in other mammals is using a molecular marker such as the SRY gene of the Y chromosome of males. This study aims to identify the sex in shrews through polymerase chain reaction (PCR) amplification of the SRY gene of Mexican endemic ...
However, due to the male-determining role of the Y chromosome in M. cabrerae, at least one copy of the SRY gene located on this chromosome should be functional and act as the sex-determining gene in this species [16]. Our previous molecular analyses of SRY from M. cabrerae were ...
(SRY). The gene located on the Y chromosome that is responsible for male sex determination in almost all placental mammals. Imprinting An epigenetic process that, through methylation and histone modification, tags the chromosomes inherited from the mother or the father and results in differential gen...
more specifically on a gene on the Y chromosome encoding a testis-determining factor, TDF. The human sex-determining region has been delimited to a 35-kilobase interval near the Y pseudoautosomal boundary3. In this region there is a candidate gene ...
The Sry gene is on the Y chromosome short arm. Bottom: XX progeny inherit X chromosomes from the mother (Xm) and father (Xp). The XX mouse is a mosaic of cells expressing one of the parental X chromosomes. Green shows the patches of tissues in which Xp is active, and lavender shows...
XY gonadal dysgenesis and go- nadoblastoma: a study in two sisters with a cryptic deletion of the Y chromosome involving the SRY gene. Hum Genet 1995: 95: 63-66.Barbosa AS, Ferraz-Costa TE, Semer M, Liberman B, Moreira-Filho CA. XY gonadal dysgenesis and gonadoblastoma: a study in...
IN mammals, testis determination is under the control of the testis-determining factor borne by the Y chromosome1,2. SRY, a gene cloned from the sex-determining region of the human Y chromosome, has been equated with the testis-determining factor in man3
摘要:本试验以牛Sry基因和Y染色体重复序列作为雄性特异性基因,分别设计引物,建立多重巢式PCR体系, 比较二者在牛早期胚胎性别鉴定中的应用效果。试验结果表明,当扩增体系中的模板量为一个胚胎细胞的DNA 量时,以Y染色体重复序列构建的扩增体系比Sry基因具有更高的灵敏度和稳定性,更适合用于牛早期胚胎 性别鉴定。 关键...
In a study published by PNAS, Hokkaido University biologist Asato Kuroiwa and her team uncovered that most genes originally on the Y chromosome of spiny rats have relocated to other chromosomes. However, they had difficulty finding the SRY gene. ...
This makes the Y chromosome a powerful tool for investigating events in human genetic history. The study of mutation on the Y chromosome clarifies intra-allelic processes in general, and provides specific information about mutation rates that is useful in estimating the coalescent times of lineages....
