Understand the concept of independent assortment: During meiosis, homologous chromosomes are distributed into gametes independently of one another. This means that the way one pair of chromosomes separates does not affect how another pair separates.
Identify the number of homologous chromosome pairs: The problem states that the organism has five pairs of homologous chromosomes.
Apply the formula for calculating the number of different gametes: The number of different gametes that can be produced by independent assortment is given by the formula 2^n, where n is the number of homologous chromosome pairs.
Substitute the given number of chromosome pairs into the formula: In this case, n = 5, so the formula becomes 2^5.
Calculate the result of the expression 2^5 to determine the number of different gametes that can be produced by independent assortment alone.
