Question

how many homologous chromosome alignments are possible for independent assortment during meiosis?
○ one
○ two
○ three
○ four

Explanation:

During meiosis, for independent assortment, homologous chromosome pairs (bivalents) align at the metaphase plate. Each pair can align in two possible orientations (maternal and paternal chromosomes can be on either side of the plate). But the question here is about the number of possible alignments for independent assortment in terms of the basic possibility for a pair. Wait, actually, when considering the alignment of homologous chromosomes during metaphase I of meiosis for independent assortment, each homologous pair can align in two different ways (the two possible orientations for the pair). But maybe the question is simplified. Wait, no—wait, the options: the key is that for independent assortment, the homologous chromosomes (a pair) can align in two possible ways (each pair has two possible alignments). So the answer is two.

Answer:

B. two
