[an– + euploid.]

Examples

  • Such results can be related to the formation of meiotic trivalent in the hybrids leading to the production of viable aneuploid gametes and post-zygotic elimination of embryos due to chromosomal non disjunction events at meiosis.

  • However, some leukemias and lymphomas are not aneuploid, and dysregulated expression of multiple genes is likely to be the main reason why aneuploidy is a marker for cells with abnormal phenotypes.

  • If the blastomere is aneuploid, this molecular tool, called "fluorescence in situ hybridization," or FISH, will unmask it.

  • "The reason for aneuploid embryos are mostly aneuploid oocytes immature egg cells, as aneuploid sperm are relatively rare with an estimated frequency of about 2 per cent, while aneuploid oocytes are quite common with an estimated frequency of more than 20 per cent," he says.
