What is the result of a mitosis that's not accompanied by a cytokinesis?

Question

To those of you who answered my previous question on nuclear division in plant and animal cells, I really appreciate it. Thank you. I overlooked the questions and realized there was one more question about nuclear division in plant and animal cells that stumped me. Once again please help me out.

Thank you.

Answer 1

You would produce a cell which has twice the number of chromosomes = 4n (tetraploid ) and not the expected 2n (Diploid)
