To determine the number of genetically different gametes that can be produced by an individual of genotype AaBbccDDEe, we need to consider the independent assortment of alleles.

Independent assortment means that alleles for different genes segregate independently during gamete formation. In this case, we have five different genes (A, B, C, D, and E) with two alleles each (capital and lowercase letters represent different alleles).

For each gene, the individual can produce two different gametes, one carrying the capital allele and the other carrying the lowercase allele. Since we have five independently assorting genes, we can multiply the number of gametes for each gene to determine the total number of genetically different gametes.

Therefore, the total number of genetically different gametes that can be made by an individual of genotype AaBbccDDEe is:

2 (alleles for gene A) x 1 (allele for gene B) x 2 (alleles for gene C) x 2 (alleles for gene D) x 1 (allele for gene E) = 8

So, the individual can produce 8 different genetically unique gametes. Hence, the correct answer is option 3.
