    Maternal mosaicism of sex chromosome causes discordant sex chromosomal aneuploidies associated with noninvasive prenatal testing by Leilei Wang, Qian Meng, Xinxin Tang, Ting Yin, Jinglu Zhang, Shuting Yang, Xuyun Wang, Haiqian Wu, Qingxi Shi, Edmund C. Jenkins, Nanbert Zhong, Ying Gu

    Published 2015-10-01
    “…Furthermore, it was found that the false positive case with lower X chromosome concentration in NIPT was caused by maternal sex chromosomal mosaicism (45, X and 46, XX). Conclusion: Our findings indicated that maternal mosaicism of sex chromosome could cause discordant sex chromosomal aneuploidies associated with NIPT. …”

    Numerous transitions of sex chromosomes in Diptera. by Beatriz Vicoso, Doris Bachtrog

    Published 2015-04-01
    “…Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six chromosomal arms (five large rods and a small dot), but superficially similar karyotypes may conceal the true extent of sex chromosome variation. …”

    Heterochiasmy and sex chromosome evolution in Silene by Filatov, DA

    Published 2023
    “…<p>The evolution of a non-recombining sex-specific region is a key step in sex chromosome evolution. Suppression of recombination between the (proto-) X- and Y-chromosomes in male meiosis creates a non-recombining Y-linked region (NRY), while the X-chromosome continues to recombine in females. …”

    Female meiotic sex chromosome inactivation in chicken. by Sam Schoenmakers, Evelyne Wassenaar, Jos W Hoogerbrugge, Joop S E Laven, J Anton Grootegoed, Willy M Baarends

    Published 2009-05-01
    “…During meiotic prophase in male mammals, the heterologous X and Y chromosomes remain largely unsynapsed, and meiotic sex chromosome inactivation (MSCI) leads to formation of the transcriptionally silenced XY body. …”
