Contrast the differences of nondisjunction and polyploidy.
a) Nondisjunction involves the failure of homologous chromosomes to separate during meiosis, while polyploidy involves the presence of additional sets of chromosomes.
b) Nondisjunction leads to the formation of gametes with an incorrect number of chromosomes, while polyploidy leads to the presence of extra chromosomes in every cell.
c) Nondisjunction results in aneuploidy, while polyploidy results in euploidy.
d) All of the above
