And in particular, we're looking at a new ploidy.
00:09
So what does that mean? that means to have an extra or missing chromosome.
00:23
So rather than having an error on the chromosome, we have an incorrect number.
00:30
And then we're looking at a list of syndromes, and we're trying to figure out which one is not this.
00:36
So if we take a look at turner syndrome, we see that on the sex chromosome, rather than having xx or xo, they simply just have an x.
00:58
So it's referred to as x not or x0.
01:03
It really just means that they have one instead of two sex chromosomes, right? so this would qualify as missing a chromosome.
01:12
So this one is definitely anipleady.
01:16
So the next one is down syndrome.
