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: -Female gametogenesis, also known as oogenesis, results in mature eggs. As a result of meiosis, only one egg is generated from four haploid cells. The primary oocyte undergoes the first meiotic division, resulting in the formation of a secondary oocyte (haploid).
Detailed explanation-3: -Assertion :Mainly two polar bodies are released during each oogenesis in human Reason: One primary oocyte form two ova.
