Gametes are always haploid. Gametes should be haploid for maintaining the chromosome number of the species.This is achieved by meiosis the reduction division in germ cells. Meiosis is reduction division that occurs only in germ cells where gametes are produced with half the chromosome number to that of the parent cell.ametes should be haploid for maintaining the chromosome number of the species.This is achieved by meiosis the reduction division in germ cells.
