What is XXY in drosophila?

XXY in Drosophila refers to a specific chromosomal configuration where an individual has two X chromosomes and one Y chromosome. This condition typically results from nondisjunction during meiOSis, leading to the formation of aneuploid individuals. XXY flies often exhibit abnormal phenotypes, including altered fertility and development, and are used in genetic studies to understand sex determination and chromosomal abnormalities.
