We have some results from gel electrophoresis here, and to be much to know, we want to know who the father of the child is.
00:08
So i'm going to look at the child's bands here, just to copy them out.
00:12
So if they have two, then one on its own, then two more, and then one a little bit further down.
00:18
Now, each of these bands comes from one of the parents.
00:21
So each band is inherited from a parent.
00:30
Now, they don't get all of the parents ' bands, because after all, a child, only inherits half of the genetic material of the parents.
00:38
But every band you see in the child's gel electrophoresis comes from a parent, unless there has been a spontaneous mutation, which can absolutely happen, but you'd expect the vast majority to come from one of the parents.
00:51
Now we have the information for the mother.
00:54
So some of these bands could easily have been inherited from the mother.
00:58
So we should look at those.
01:00
So the mother is likely responsible for this one.
01:04
So this one we can rule out because the mother has a band here as well.
01:08
And for this one here, the mother has a band, so could have passed this on, and for this one here.
01:17
So those three, i'm going to ignore...
