A. The centromeres of these three chromosomes lack attachment sites for spindle microtubules therefore leading to a higher than normal segregation error rate.
B. These three chromosomes have the highest probability to be mis-segregated while anaphase I and II of meiosis.
C. Cells are more likely to survive with abnormal numbers of these three chromosomes whereas segregation errors of the other 20 human chromosomes are totally lethal.
