X chromosome duplications affect a region of the chromosome they do not duplicate in Caenorhabditis elegans.

abstract：:Many complex human traits exhibit differences between sexes. While numerous factors likely contribute to this phenomenon, growing evidence from genome-wide studies suggest a partial explanation: that males and females from the same population possess differing genetic architectures. Despite this, mapping gene-by-sex (...
