Verified step by step guidance1
Understand the concept of ploidy: Ploidy refers to the number of sets of chromosomes in a cell. Diploid cells have two sets of chromosomes, one from each parent.
Identify the type of cell: The problem asks about diploid cells, which are typical of somatic (body) cells in humans and many other organisms.
Recall the definition of diploid: Diploid cells are denoted as 2n, where 'n' represents a single set of chromosomes. Therefore, 2n means there are two sets of chromosomes.
Compare with other ploidy levels: Haploid cells (like gametes) have one set of chromosomes (n), while polyploid cells can have more than two sets, such as triploid (3n) or tetraploid (4n).
Conclude based on the definition: Since diploid cells are defined as having two sets of chromosomes, the correct answer is 'Two sets'.
