Verified step by step guidance1
Understand that independent assortment refers to the random orientation of homologous chromosome pairs during metaphase I of meiosis.
Recognize that the number of different alignments possible is determined by the formula 2^n, where n is the number of homologous chromosome pairs.
Identify that in this problem, the organism has 3 pairs of chromosomes, so n = 3.
Apply the formula: calculate 2^3 to determine the number of possible alignments.
Conclude that the number of different alignments of homologous chromosomes is 8, as calculated from the formula.
