Answer:
Haploid
Explanation:
Gametes are mainly produced by the process of meiosis in the gamete mother cells. Meiosis reduces the chromosome number to the half in the gametes and produces haploid gametes. Haploid cells are the ones that have only one complete set of chromosomes. The fusion of haploid male gamete with a haploid female gamete restores the diploid chromosome number in the zygote.
For example, each of the human sperms and egg cells has 23 chromosomes. Somatic cells in humans have 46 chromosomes. The fusion of a sperm carrying 23 chromosomes with an egg having 23 chromosomes restores the 46 chromosomes in the zygote.
