Independent assortment of chromosomes is a result of
a) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis i.
b) the random nature of the fertilization of ova by sperm.
c) the random distribution of the sister chromatids to the two daughter cells during anaphase ii.
d) the relatively small degree of homology shared by the x and y chromosomes.
