Hello everyone.
00:03
Today we're going to discuss about oogenesis.
00:11
Oogenesis is the process of formation of eggs.
00:15
It starts from primordial germ cells.
00:28
These are deplored cells.
00:36
They get converted into oogonium, that is also deploid cell, that is, ovoonium.
00:52
This ogonium enlarges in its size and results in the formation of primary oocyte that is also a deployed cell.
01:17
This primary oocyte undergoes myosis 1 and deserves in the formation of two secondary oocytes.
01:26
Here is myosis 1 and resulting in the formation of 2 oocides that are applied.
01:45
These are secondary oocytes and each secondary oocytes undergoes myosis 2 to form 2 ovum.
01:59
So we have got total of 4 oom that are also applied.
02:05
Now, as far as spermatogenesis is concerned, spermetogenesis starts with a deployed cell that is called spermatogonium.
02:42
This spermatogonion undergoes mitosis to form a deplied primary spermatocyte...
