Verified step by step guidance1
Recall the definitions of ploidy: a diploid cell (2n) contains two sets of chromosomes, one from each parent, while a haploid cell (n) contains only one set of chromosomes.
Understand that mitosis is a process of cell division that produces two genetically identical daughter cells, maintaining the same ploidy as the parent cell.
Recognize that meiosis is a specialized form of cell division that reduces the chromosome number by half, producing haploid gametes from a diploid parent cell.
Note that both mitosis and meiosis start with a parent cell that is diploid (2n), because meiosis needs to reduce the chromosome number from diploid to haploid.
Conclude that the correct statement is: 'Both mitosis and meiosis begin with a parent cell that is diploid.'
