WebAt meiosis, where there is pairing of homologous chromosome segments (normal chromosomes form a bivalent), followed by crossing-over, translocations may form a quadrivalent (tetravalent, in Greek) and this leads to segregation problems. At meiosis anaphase I, chromosomes separate without centromere separation; this separation … Web21 dec. 2024 · Klinefelter's syndrome is a genetic condition that only affects males. Affected males have an extra X chromosome. It is sometimes just called XXY. Between 1 in 500 and 1 in 1,000 boys are born with Klinefelter's syndrome (KS).
