By the way this is a science lab.
I'm learning how to karyotype, so I had to match up the chromosomes to their mates. But when I cut them out I noticed I had an extra chromosome. When I was done all of the chromosomes were matched up with their mate except for that one chromose. I checked to see if maybe it was 3 of the same chromosome, but there wasn't. So what is it? Is it a leftover sex cell? If it wasn't for that leftover my person would be a female, but does that extra chromosome mean the person is a hermaphrodite? What sex is it?

Your "patient" has Klinefelter Syndrome. That is when the individual has XXY (extra X chromosome). It is a male. Here's a link for info.

If you can't find 3 time time the same chromosome, you most probably have XXY or XYY or something like that. Try if you can match the mystery chromosome with the X or th Y. If it does, you found the solution of your problem.
As for the sex, most scientist will designate an individual with at least one Y-chromosome as a male, because the individual will have a penis as the presence of one copy of the SRY-gene will suffice to develop male attributes in the indivudal. However, the individual could feel different about its gender and not want to be classified as male or female.

You need to look at the banding pattern, if available, People can be XXY or XYY as noted. Translocations are also possible, part of chromosomes get stuck to another. So one chrom. will appear large, and another small. This is frequently seen with cancer.

Male.
If the unpaired chromosome is small, you have an XXY male.
If the unpaired chromosome is large, you have an XYY male.
Did you assess the banding patterns?
