00:01
So this question is almost definitional.
00:05
If you were in a test situation and you got stuck on this one, it would be very hard to maybe guess your way through it.
00:15
So partially it's just knowing.
00:18
But in animals, how are our sex cells made? so let's just go through the different options.
00:27
Again, it's very definitional.
00:29
But let's just take a go through some of the definitions, right? so one, hopefully this one will stand out that you go into it and know that animal sex cells are made through the process of meiosis.
00:43
And what is myosis? so let's just go choice a.
00:46
What is it in this process? we're going to have the number of chromosomes.
00:54
So we start off with a certain number.
00:56
We're going to end up with half that.
00:58
It allows for genetic mixing among the chromosomes.
01:09
And then once you get your haploid gametes, so haploid just means they have half the number, they need to undergo fertilization to begin to make a baby.
01:24
Okay, so that's a different process, but that's what we're making.
01:28
Okay.
01:29
So that's the right answer.
01:31
But let's look at choice b for mitosis.
01:35
So mitosis, we're going to make a copy or aiming to make a direct copy of the cell.
01:43
Number of chromosomes is maintained, chromosomes.
01:54
And ideally, you actually aren't going to get any genetic diversity...
