How many homologous chromosome alignments are possible for independent assortment during meiosis?
1. one
2. two
3. three
4. four

The correct answer would be 2. two.

Homologous chromosomes refer to the pair of chromosomes, one inherited from each parent. They are similar in length, centromere location, and gene position. However, the genes may contain different alleles.

One homologous pair can be aligned in two possible ways during meiosis which enables the random distribution of chromosomes in daughter cells during the formation of gametes.  

Alternatively, one can find the possible number combinations of chromosomes by the formula 2ⁿ, where n is the number of chromosome pairs.

Here, the number of chromosome pairs is equal to 1. Thus, the number of possible combinations or alignments would be 2¹ which comes out to be 2.

well, i believe that the answer is 2. : 3
