What is probability of couple where male is karyotypically normal and the female in pericentric inversion in heterozygous condition produced child with disability if 50% chance of crossing over takes placed within pericentric inversion. (Note: Duplication and deletion in gamete will results in disability)

#Unit 8. Inheritance Biology
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
