Answer for Class 12 Biology Students

Oogenesis:

Discontinuous process, i.e.; growth arrests at prophase I and metaphase II.

 Oocyte differentiates along with cell division.

 Process completes in years.

 Asymmetrical cytokinesis results in formation of polar bodies.

 One primary oocyte forms only one ovum.

 Oogenesis starts in female foetus during embryonic development.

 Oogenesis starts in ovary but completes outside the ovary in fallopian tube during fertilization.

Spermatogenesis:

Continuous process.

 Differentiation occurs after completion of meiosis.

 Process is completed in 74 days.

 Cytokinesis is symmetrical.

 One primary spermatocyte forms 4 sperms.

 Spermatogenesis starts at puberty.

 Spermatogenesis starts and completes within testes.
