Because, it’s the product of fusion of two haploid cells.

Explanation:

A zygote is a eukaryotic cell formed by a fertilization event between two gametes. Gametes are haploid.

Male gamete is called sperm and female gamete is called egg.

E.g. Human sperm cell and egg cell contain #23# chromosomes each. After fertilisation, zygote formed will contain #46# chromosomes.

#"23 (sperm) + 23 (egg) = 46 (zygote)"#
