Question

Independent assortment of chromosomes is a result of24)A)the random nature of the fertilization of ova by sperm.B)the random distribution of the sister chromatids to the two daughter cells during anaphase II.C)the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I.D)the relatively small degree of homology shared by the X and Y chromosomes.E)All of the above

Answer 1

The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I

Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.  

When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.
