Are gametes haploid offspring haploid or diploid?

Gametes are haploid cells produced by the process of meiosis. They unite during fertilization to form a diploid zygote, which divides to form the embryo, and is the first cell of the new offspring of the organisms that produced the gametes. For example, human females produce ova, the female gametes, and human males produce sperm cells, the male gametes. During fertilization, one ovum and one sperm cell unite to form a zygote which divides by mitotic cell division, forming the embryo. The baby that is produced is not considered an offspring of the gametes, but an offspring of the mother and father that produced it.
