Which of the following statements about oogenesis is false?
A
Oogenesis produces four viable gametes from one primary oocyte.
B
Oogenesis involves two rounds of meiotic division.
C
Oogenesis begins during fetal development and is completed after fertilization.
D
Oogenesis results in the formation of one mature ovum and polar bodies.
Verified step by step guidance
1
Understand the process of oogenesis: Oogenesis is the development of the female gametes, or ova, through a series of stages starting from the primary oocyte.
Recognize the stages of oogenesis: It involves two rounds of meiotic division. The first meiotic division results in a secondary oocyte and a polar body. The second meiotic division occurs after fertilization, resulting in one mature ovum and additional polar bodies.
Clarify the outcome of oogenesis: Unlike spermatogenesis, which produces four viable sperm cells, oogenesis results in one mature ovum and three polar bodies, which are not viable gametes.
Identify the timing of oogenesis: Oogenesis begins during fetal development, with primary oocytes arrested in prophase I until puberty. It is completed after fertilization.
Evaluate the statements: The false statement is 'Oogenesis produces four viable gametes from one primary oocyte,' as oogenesis results in one mature ovum and polar bodies, not four viable gametes.
