Mammalian females have two X chromosomes, while males have only one X plus a Y chromosome. In order to balance X-linked gene dosage between the sexes, one X chromosome undergoes inactivation during development of female embryos. This process has been termed X-chromosome inactivation (XCI...
The human Y chromosome harbors genes that are responsible for testis development and also for initiation and maintenance of spermatogenesis in adulthood. The long arm of the Y chromosome (Yq) contains many ampliconic and palindromic sequences making
46,XX male syndrome is often a result of a translocation of the SRY gene from the Y chromosome onto the paired (although not homologous) X chromosome. From:Encyclopedia of Reproduction (Second Edition),2018 About this page Set alert
Of the hypotheses put forward to explain why occasional individuals with two X chromosomes are nonetheless male, the one that has attracted most attention is the possibility1 that one of the X chromosomes has obtained a small piece of Y chromosome which
The PAR1 and PAR2 of the Y chromosome are short regions of homology between the mammalian X and Y chromosomes; the PAR1 is located on the tip of the p arm and the PAR2 on the tip of the q arm (Fig.1). Due to the diversity in the genetic sequences of the X and Y chromosomes...

X-linked genes,unlike in autosomal genes,would not be masked by a normal allele.Many researches have been conducted on the relationship between spermatogenesis and the genes on the X chromosome,but the involvement of the X chromosome in male infertility remains less understood and deserves further ...
摘要: Males with two X-chromosomes ejaculate more often than males with a single X-chromosome. Male mice with two X-chromosomes are faster to attain ejaculations than males with one X-chromosome. In both sexes, an additional X-chromosome facilitates display of mounting and thrusting....
longipes. First, we identified the scaffold that corresponds to the X chromosome (see material & methods). Interestingly, our analysis detected enrichment in the X chromosome with female-biased genes of the third legs, but not the two other legs, compared to the autosomes (Fig. 5a). The ...
