Question 2 Which is true of spermatogenesis and oogenesis? (choose all that apply) polar bodies are simply eggs waiting to develop and mature spermatogenesis produces 4X the gametes per spermatocyte/oocyte both produce polar bodies as part of meiotic division both depend on meiosis to reduce chromosome number 2 pts

Transcript

00:01 In order to answer this question, let's talk about gametogenesis.

00:03 This question says, which are following statements about human gametogenesis are true and select all that apply.

00:08 Remember that in gametogenesis, let's talk about in general, okay? you are going to start with an oogonia or spermatogonia.

00:16 Okay, so this oogonia or spermatogonia and then it is going to differentiate into a cell that is called primary, gametocyte.

00:37 If you are in a woman, then this is going to be a primary oocyte, and if you are in a man, you're going to have primary spermatoide.

00:45 So then this primary gametocytes is going to enter myosis, one, and it is going to produce secondary gametocytes, okay, that in females, this is going to be a little different, but we're going to talk about that later.

01:04 And then each of these secondary gametocytes are going to enter the process of my genocytes.

01:09 Okay.

01:09 And you're going to produce gametes, specifically spermatids and also oocytes.

01:16 Okay? so let's look at these questions here.

01:18 It says polar bodies of products of oogenesis.

01:21 And well, this is actually true because here in this process of myosis, in case of females, once you have here your primary ovosite, and only one is going to convert into the secondary gametocytes, and the second one is going to be a polar body.

01:43 Okay, and after this secondary gametocytes undergoes myosis 2, it is going to produce only one oxide and this one is going to be a polar body.

01:53 Okay, so you are going to produce also polar bodies.

01:56 Like it says, ogenesis has a primary oocyte until sexual maturity.

02:01 And this option is also true.

02:03 Because in males, for example, everything starts at poverty.

02:08 Okay...
