For this question, we have a karyotype.
00:05
So we can see all the chromosomes of this person, and we need to see what is true about this.
00:10
Does it show a normal female, a normal male, a person with down syndrome, a person with a gene mutation, or a person who suffers from a condition that results from non -distjunction? okay, so let's look for karyotype.
00:26
First of all, for d, we would not be able to tell.
00:29
We would not be able to see most gene mutations, unless it was a very cariotype.
00:32
A very serious deletion, for example.
00:37
So i'll ignore that for now.
00:39
Now, if you look at these, one thing you may notice is the sex chromosomes.
00:44
You can see that there is an x chromosome, but there is no y chromosome...
