Answer:
One cell(Haploid)
Explanation:
Gametes cells consist of one cell, it is half the chromosome number of the body cell. Gametes are produce through reduction cell division called meiosis and it results in the production of four daughter cells that are haploid with each of the cells contain a haploid number of chromosomes.
During fertilization, the female cell contains haploid number of cells and the male contains haploid number of cell fuses together to form a diploid organism.
