. Human geneticists interested in the effects of abnormalities in chromosome number often karyotypetissue obtained from spontaneous abortions. About35% of these samples show autosomal trisomies,but only about 3% of the samples display autosomalmonosomies. Based on the kinds of errors that cangive rise to aneuploidy, would you expect that thefrequencies of autosomal trisomy and autosomalmonosomy should be more equal? Why or why not?If you think the frequencies should be more equal,how can you explain the large excess of trisomiesas opposed to monosomies?
