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.

E) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I, the random nature of the fertilization of ova by sperm, the random distribution of the sister chromatids to the two daughter cells during anaphase II, and the relatively small degree of homology shared by the X and Y chromosomes.

The answer is A) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I.

The law of independent assortment is the second Mendel's law. In independent assortment the alleles for different traits are passed independently to the offspring. It occurs during meiosis I. When in metaphase of meiosis I the chromosomes line up, mother's chromosomes can be on one side, and father's chromosomes on the other side of the equator or they can be mixed in a number of ways.
