What is the original cell called at the beginning of meiosis when it has two copies of the parent's DNA?

The original cell at the beginning of meiosis that contains two copies of the parent's DNA is referred to as a diploid cell. In this context, a diploid cell is one that has two complete sets of chromosomes, one from each parent. This state is crucial as meiosis begins with diploid cells, which will undergo two rounds of cell division to produce haploid gametes.

While germ cells are involved in the process of meiosis, the term specifically refers to the category of cells that give rise to gametes; it does not denote the ploidy of the cell. The gametes themselves are the cells formed at the end of meiosis, and sperm cells are a specific type of gamete. Therefore, while germ cells may encompass the cells that undergo meiosis, the original diploid cell is the more precise answer to denote the starting point of the meiotic process.
