A faster way to do it is by (2^n) where 2 is the number of alleles and n is the number of genes, so we have 2^3 = 8. so we have 8 possible combinations.
Assuming you are asking how many different types of gametes can an individual with the genotype AaBbCc make. To answer we must first make one assumption: each gene resides on a different chromsome. The reason we do that is to simplify the analysis by making use of Mendel's Law of Independent Assortment. The possible genotypes in the gametes are thus:
ABC
ABc
AbC
Abc
aBC
aBc
abC
abc
Independent Assortment allows us to determine the answer by simply listing out all of the possible combinations of alleles. However, if all or some of the genes are on the same chromosome, the answer becomes much more difficult, because then one has to know the probability of recombination between the genes. The closer in physical proximity on the chromosome the genes are, the less probable recombination (crossing over) will occur between them, because it's more difficult for crossing over to happen on very short stretches of DNA.
Ab and ab There would be about a 50/50 ratio of each.
An individual with the genotype Aa can produce two types of gametes: one carrying the A allele and one carrying the a allele. This individual will produce equal numbers of gametes with the A allele and gametes with the a allele due to Mendel's law of segregation.
Each time a gamete is formed, one allele from each gene (i.e. either A or a) is included.This means for an individual with AaBbCc, there are 8 different gametes:ABCABcAbCAbcaBCabCaBcabc
With Hh genotype, two types of gametes can be formed: H gametes and h gametes. This is because each parent can pass on either the dominant allele (H) or the recessive allele (h) to their offspring.
Gametes are formed during the process of gametogenesis, which occurs in the ovaries (for eggs) and testes (for sperm) in humans. Gametogenesis involves the individual cells undergoing a specialized type of cell division called meiosis to produce haploid gametes with half the number of chromosomes as the parent cell.

8 kinds of gametes will be formed, each showing a unique combination of alleles from the given genotype (A, B, C, D, E).
Each time a gamete is formed, one allele from each gene (i.e. either A or a) is included.This means for an individual with AaBbCc, there are 8 different gametes:ABCABcAbCAbcaBCabCaBcabc
With Hh genotype, two types of gametes can be formed: H gametes and h gametes. This is because each parent can pass on either the dominant allele (H) or the recessive allele (h) to their offspring.
Four can be formed RY, Ry, rY and ry.
How are gametes formed?
The Male Gametes are formed in the testicles.
Gametes are formed during the process of gametogenesis, which occurs in the ovaries (for eggs) and testes (for sperm) in humans. Gametogenesis involves the individual cells undergoing a specialized type of cell division called meiosis to produce haploid gametes with half the number of chromosomes as the parent cell.
Each gamete contains one allele from each of the genes (in this case one version of each letter). Any gene for which the individual is homozygous (has two of the same alleles) can only produce gametes with that allele. So in this case the organism has BB and dd - so will always have a B and d in the gamete. So the possible gametes are: ABCdE ABcdE ABCde ABcde aBCdE aBcdE aBcde aBCde
The four potential gametes of an individual that is heterozygous for two traits are formed due to independent assortment. Each gamete can inherit different combinations of alleles for those two traits, leading to genetic diversity in the offspring.
