If you are looking at a cariotype which shows the chromosomes of an individual, there's a few things that you look for.
00:08
Now, the first thing that everyone looks for is whether this person is a male or female.
00:17
So if they are male, then all the way at the end where you see the sex chromosomes, then you should see one sex chromosome that is tall and one that is short showing that they have an x chromosome and a little y chromosome.
00:30
However, if it is a female, then you should see two matching tall ones showing that they have two x chromosomes.
00:38
Now, for the rest of it, normally when we look at a chariotype, we are looking for different syndromes.
00:44
We're looking for common syndromes that affect the genes and usually the number of chromosomes an individual has.
00:51
So some of the most common ones that you might find is kleinefelter's syndrome.
01:01
So with kleinefelter syndrome, you will have at least one extra sex chromosome.
01:11
So that means that you might have an individual who has x, x, x, y, or you might have an individual who has x, x, x, x, or even x, y.
01:24
Right? you just have extra sex chromosomes.
01:26
Usually it's only one.
01:28
There is the possibility for it being two.
01:31
But there are other syndrom that you might look for like downs syndrome...
