What kind of information can we get from a carriotype? it says choose all correct answers, but the options aren't there, so i'm just going to give you a list of things that you can notice from a carriotype.
00:12
The easiest one that you can notice is a whole chromosome loss, or an entire whole chromosome duplication.
00:23
Either of these are very visible.
00:24
Perhaps you'll find a whole chromosome loss in a tumor cell.
00:28
That's quite an extreme change to a cell.
00:31
Or perhaps you'll find a whole chromosome duplication.
00:34
Most famously, trisomy 21 is down syndrome, so you might pick that up during the chariotyping of a prenatal screening.
00:43
But this isn't all you can see.
00:45
Because you're looking at the size, the shape, and the structure of chromosomes, that's what a carotype does.
00:53
You're physically looking at the chromosomes...
