Aneuploids may arise through nondisjunction, the failure of homologous chromosomes or sister chromatids to separate in meiosis. Following some statement are 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 other half normal haploid
C) Meiosis I non-disjunction leads to produce half of gametes n+1 other half n-1
D) Either meiosis I or meiosis II non-disjunction leads to produce all aneuploidy gamete
