aneuploids may arise through nondisjunction, the failure of homologous chromosomes or sister chromatids to separate in meiosis. which of following the incorrect about nondisjuction ?

#Unit 8. Inheritance Biology
  1. Meiosis I non-disjunction leads to produce all gamete become aneuploidy

  2. Only Meiosis II non-disjunction leads to produce 50 % gamete become aneuploidy other 50% become normal diploid

  3. Only  Meiosis I non-disjunction leads to produce 50 % gamete n+1 and other 50% become n-1

  4. Either meiosis I or meiosis II nondisjuction  lead to produce aneuploidy gamete.
