Verified step by step guidance1
Understand that gametes are reproductive cells that carry half the genetic information of an individual, and in humans, this is determined by the number of chromosomes.
Recall that humans have 23 pairs of chromosomes, and during gamete formation, these chromosomes assort independently.
The principle of independent assortment states that each pair of alleles segregates independently of any other pair during gamete formation.
To calculate the number of different gametes that can be produced, use the formula 2^n, where n is the number of chromosome pairs.
Substitute the number of chromosome pairs (23 for humans) into the formula: 2^23. This will give you the number of different gametes that can be produced based on independent assortment alone.
