Hi there.
00:03
In this question, we have the map distances separating four genes on the same chromosome, and we're trying to determine the order in which those genes may lie, the most likely order.
00:16
So what i like to start to do, what i like to do is start with the largest difference.
00:21
So we know h to g is separated by 20 map units.
00:30
Okay, so this is really like a puzzle, maybe a logic puzzle, putting these different.
00:34
Pieces together to make sure that they all agree with the distances.
00:41
Okay, so the next thing i notice, i'm just going to start with h.
00:48
And i notice that h to b is eight map units.
00:55
So h to b, there are eight map units separating those.
01:03
And then b to a has 10.
01:20
All right.
01:22
And let's see what we're what a to g is.
01:24
A to g is two.
01:30
I think there's another one here.
01:31
Oh, a to h.
01:33
A to h is 18...
