Question

Unequal cytokinesis occurs in the

• A. Production of sperm cells
• B. Production of egg cells
• C. Mitosis of an epidermal cell
• D. Binary fission in bacteria
• E. None of the above

Answer 1

Answer: (B)

Production of egg cells

• Production of egg cells i.e. oogenesis is an example of unequal cytokinesis.
• Here, primary oocyte undergoes meiosis-I to form a large haploid secondary oocyte and a small first polar body.
  
• Secondary oocyte undergoes meiosis-II during fertilisation resulting in formation of a larger ovum (egg) and tiny second polar body.
  
• So, the correct option is 'Production of egg cells'.
