Consider the following steps regarding the production of diploid plants via endomitosis as described in the text:

#Plant Biotechnology
  1. A stem segment is cultured on a medium containing Auxin and Cytokinin.
  2. Callus formation is induced.
  3. Chromosome doubling occurs during the callus phase.
  4. Diploid homozygous plants are regenerated.
