    Okay. So, the chart that you posted shows us all the chromosomes, in one human cell. NORMALLY, humans have 46 chromosomes, which is the same as 23 PAIRS of chromosomes. Take a look at the chart. There are 23 numbered groups, on the chart. And every group SHOULD have two chromosomes, you see? For example, take a look at group number 1, and ONLY at group number 1. Group number 1 has two chromosomes. Now look at group number 2. Group number 2 also has two chromosomes. They should ALL be like that. EVERY numbered group should have TWO chromosomes. ~~~~~~~~~~~ Take a look at group number 23. Do you see something weird about group number 23? There's only ONE chromosome! That's not normal. Not at all. ~~~~~~~~~~ Is the chromosome in group number 23 long, or short? It's long. That means it's an X chromosome. (Because Y chromosomes are short.) So, again, there is only ONE chromosome, in group number 23. There SHOULD be two. In group number 23, we only have an X chromosome. So, there's a missing chromosome. A FEMALE would have (X X) A MALE would have (X Y) ~~~~~~~~~~~~ Now, let's take a look at all our choices: What are we looking at? -- a female with Turner's syndrome -- a male with Klinefelter's syndrome -- a female with Down syndrome -- a normal male ~~~~~~~~~~~~~~~ Let me tell you about the FIRST choice -- Turner's Syndrome. Turner's Syndrome is where a FEMALE is missing an X chromosome, in group number 23. Does that sound familiar to you? ~~~~~~~~~~~~~~~ Klinefelter's Syndrome is where a MALE has an extra X chromosome, in group number 23. ~~~~~~~~~~~~~ Down Syndrome is where a person has an extra chromosome, in group number 21. ~~~~~~~~~~ And NORMAL people should have 2 chromosomes in each group.

    "Klinefelter's Syndrome is where a MALE has an extra X chromosome, in group number 23." is that what you see on the picture?

    @UmmmHELP Take another look at the chart that you posted: http://assets.openstudy.com/updates/attachments/50f629efe4b081e396d7e559-ummmhelp-1358309936406-bio.gif Do you see how there are numbered groups, on the chart? Every group SHOULD have 2 chromosomes. Look at group #1. You can see that in group #1, there are two chromosomes. That is normal. Every group should have two chromosomes. Now, take a look at #23. We notice that in group #23, there is only one chromosome. You see there? That's not normal. There SHOULD be two. So, the person, whose chart this belongs to, has a genetic disorder. We know that, because this chart does not look like a normal person's chart. Group #23 does not have two chromosomes. There is only one chromosome in group #23. And that means that one is missing. ~~~~~~~~~~~ Using that information, what you can do is go back to the part where I explained all of your choices, and see if you can pick out the right one, this time.
