Which statement best expresses the major difference between mitosis and meiosis?
 
  a. Mitosis is cell division in animals meiosis is cell division in humans.
  b. Mitosis is the process by which a single cell with X number of chromosomes divides into two cells, each withthe same number of chromosomes meiosis is the process by which a single cell with X number ofchromosomes goes through two stages of division, producing four new cells each with X/2 (half the originalnumber) of chromosomes.
 c. Mitosis is the process by which chromosomes are divided meiosis is the process by which DNA is divided.
  d. Mitosis is the process by which cells divide into four different sets of genetic information (called codons)meiosis is the process by which cells are joined together and multiplied to create growth and development.
 e. Mitosis and meiosis are both types of cell division in which a single cell with X number of chromosomes dividesinto two cells, each with one half of the original chromosomes mitosis is associated with the creation of sexcells that determine the sex of the offspring, and meiosis is associated with cell growth and development.
