Verified step by step guidance

Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell.

Recognize that before meiosis begins, the parent cell is in the diploid state, meaning it contains two sets of chromosomes, one from each parent.

Identify that homologous chromosomes are pairs of chromosomes that have the same structure and gene sequence, but may have different alleles.

Note that the parent cell before meiosis has not yet undergone DNA replication, so it contains homologous chromosomes, not duplicated sister chromatids.

Conclude that the best illustration of the parent cell before meiosis begins is a diploid cell with homologous chromosomes, as it has not yet entered the stages where sister chromatids are formed or separated.
