. 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.

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?
