Answer :Aneuploidy often results in serious problems such as Turner syndrome, a monosomy in which females may contain all or part of an X chromosome. Monosomy for autosomes is usually lethal in humans and other animals. Klinefelter syndrome is a trisomy genetic disorder in males caused by the presence of one or more X chromosomes. The effects of trisomy are similar to those of monosomy. Down syndrome is the only autosomal trisomy in humans that has a substantial number of survivors one year after birth. Trisomy in chromosome 21 is the cause of Down syndrome; it affects 1 infant in every 800 live births

The other two men, (Man 2 - Ai and Man 3- ii), have the possibility of being a father.
Nonsense mutation: a sense codon changes into a chain-terminating codon.
Missense mutation: a single nucleotide changes the codon and the corresponding amino acid
Silent mutation: A change in that does not result in a change of amino acids (ex: AAA and AAG both code for lysine)
