    GlossarySex Chromosome Aneuploidy

    condition with abnormal number of X or Y chromosomes

    Sex Chromosome Aneuploidy refers to a condition where an individual has an abnormal number of sex chromosomes (X or Y) instead of the typical XX or XY. This can lead to various developmental and health issues, such as Turner syndrome (45,X) or Klinefelter syndrome (47,XXY). These abnormalities can affect physical development, fertility, and sometimes cognitive function.

      research Sex-Limited Chromosomes And Non-Reproductive Traits

      10 citations , July 2022 in “BMC Biology”
      The document discussed how sex-limited chromosomes, like the Y chromosome, influenced non-reproductive traits in various sex determination systems (XY, ZW, UV). Traditionally associated with sex determination and reproduction, these chromosomes were found to also impact traits unrelated to reproduction. The study explored evolutionary processes that maintained variation in these chromosomes and the molecular mechanisms through which they affected non-reproductive traits.
