So we're going to be looking at how migration is going to affect a population.
00:10
And we're going to look at a few different scenarios.
00:12
So in the first scenario, we are looking at 10 % migration, and we're going to be looking at that in a small population and a large population.
00:28
So if you have a very large population, say, you know, tens of thousands of people, if 10 % are migrated in or out, and that will change the dynamic.
00:42
In this case, because it is 10%, you are definitely going to throw off your allele frequencies.
00:48
You're going to throw off the genotypic frequencies.
00:51
So there will be some kind of change in allele and genotypic frequencies.
00:57
Now, it depends on what the alleles and genotypes are of the people coming in or leaving.
01:07
So it might not change all that much, but it also has the potential to change up to, you know, 10%.
01:15
In a very large population, 10 % is a significant number, but because the population is so large, it has a lot of stability.
01:25
And that's the thing you really want to focus on here.
01:31
The larger the population, the more stable it is.
01:34
So you're definitely going to throw off the equilibrium by introducing new people and taking people out, but a large population can very quickly come to a new normal and very quickly meet its new equilibrium.
01:46
And so now it's just chilling there, and it's pretty well off.
01:49
If, however, you have a small population, say, a couple hundred individuals, and you change 10 % of them, that 10 % is a very small amount of people.
01:59
It might be, you know, 10, 20 people.
02:03
But you have a chance of changing up to 10 % of all the alleles.
02:11
So now they might be totally different than what they were before.
02:14
In that case, this will become potentially a significant change.
02:25
So there is a change in the frequencies, just as there was with a large population...
