Primordial germ cells are diploid, but why the germ cells are haploid?

Primordial germ cells are diploid (2n) and in the process of meiosis cell division, they create female and male gamete cells. In meiosis cell division, the nucleus is divided twice but the chromosomes are divided only once. As a result, the daughter cells get half of the number of chromosomes of the mother cell. This is why primordial or mother germ cells are diploid and gamete or germ cells are haploid.
