__ 22.) What does the n stand for 2n? A.) Total number of chromosomes B.) Number of types of chromosomes C.) Number of cells produced D.) Number of steps in meiosis

The correct answer is **B.) Number of types of chromosomes**.<br /><br />In the context of genetics and chromosome numbers, "2n" refers to the diploid number of chromosomes. "n" represents the haploid number, which is the number of *types* of chromosomes. A diploid cell has two of each type of chromosome (one from each parent), hence 2n.<br />
