How many genotypically different gametes could be produced by the individual represented by xxyyzz?

Only 1 type of gamete can be produced

Explanation:

Three genes are present in this organism: x, y and z. In the genotype given all three genes are in homozygous condition i.e. both the alleles of a gene are same. In this case, the organism will produce only one type of gamete which will be xyz. Hence only one type of gamete will be producedHad the gene composition been heterozygous at some location, more than one type of genetically different gametes would have been produced.
