Aneuploids may arise through nondisjunction, the failure of homologous chromosomes or sister chromatids to separate in meiosis. which of the following statements is correct?

a) Meiosis I non-disjunction leads to produce all gamete become aneuploidy

b) Meiosis II non-disjunction leads to produce half of gametes n+1 and n-1 while other half normal haploid

c) Either meiosis I or meiosis II non-disjunction leads to produce all aneuploidy gamete

d) Meiosis II non-disjunction leads to produce all gamete become n+1 and n-1
