Oogenesis results in the formation of:
|
|
1 ovum; 2 polar bodies
|
|
|
2 ova; 2 polar bodies
|
|
|
1 ovum; 3 secondary oocytes
|
|
|
4 ova
|
Explanation:
Detailed explanation-1: -The first polar body may divide to form two second polar bodies. On further division(meiosis II), secondary oocytes again form a mature ovum and one polar body. Therefore, one ovum and three polar bodies are formed after one oogenesis cycle.
Detailed explanation-2: -So, the total number of polar bodies formed are 3.
Detailed explanation-3: -Oogenesis starts with the process of developing primary oocytes, which occurs via the transformation of oogonia into primary oocytes, a process called oocytogenesis. From one single oogonium, only one mature oocyte will rise, with 3 other cells called polar bodies.
