A Mules have a n1
B Nondisjunction of a single chromosomes produces the aneuploid hybrid.
C The polyploid mule has a deficient meiosis because of having an extra set of chromosomes.
D While the mule has 2n=63 chromosomes, it can still produce viable gametes. However, they produce 4n=126 offspring that are unable to survive.
E None of the above can explain the sterility of mules.
