Verified step by step guidance1
Identify the haploid number (n) of the organism by dividing the diploid number (2n) by 2. For a mosquito with 2n = 6, calculate $n = \frac{6}{2}$.
Understand that independent assortment refers to the random distribution of maternal and paternal chromosomes into gametes during meiosis, which creates genetic variation.
Use the formula for the number of possible combinations due to independent assortment: $2^n$, where $n$ is the haploid number.
Substitute the haploid number into the formula: calculate $2^n = 2^{3}$ for the mosquito.
Interpret the result as the total number of different genetic combinations of chromosomes that independent assortment can produce in the mosquito.
