XXX conditon may arise in a human baby because of defects in meiosis 1 or meiosis 2 of gamete of mother or due to defects in meiosis 2 of gamete of father. Due to these defects the mother may have XX egg or father may have XX sperm. When these abnormal gametes fuse with normal gametes of opposite sex , the zygote formed will have XXX sex chromosome.
 
So this question have two answers which are:
(1) formation of abnormal ova in the mother
(4) formation of abnormal sperms in the father 
 
Please approve if my answer is correct.
