Hey!! so I need help with a biology question if anybody can help?? A person with the genetic disorder Klinefelter's syndrome has an extra x-chromosome. Affected individuals have the genotype XXY. What can you infer is most likely the genetic mutation that results in Klinefelter's syndrome? Non-disjunction during meiosis Complete duplication of chromosomes during polyploidy Translocation during genetic replication Crossing over during meiosis

    Okay, so let's first look at what is "crossing over during meiosis" I highlighted the part that we will be looking at, but I included the full lesson in case you needed review/or didn't get to that part yet

    okay so its not the first one...right?? because meiosis is the homologous chromosomes separate and migrate to opposite sides of the cell. and that is not non-disjunction

    Actually, I think that it is nondisjunction, because he has an extra X due to a genetic disorder. Here's the part on nondisjunction:
