Homework Help: Assignment from my biology teacher on karyotypes

  1. May 7, 2006 #1
    hi everyone. I recently got an assignment from my biology teacher on karyotypes. i am asked to pair up the chromosomes together and state its sex. But at the end i ended up with 23 paired chromosomes and 1 extra big chromosome. Can anyone tell me what is wrong with this karyotpye? Thanks in advance.

    Well, you'll be able to state its sex by knowing whether or not your karytope had (X,Y) or (X,X) sex chromosomes.

    As for the extra large chromosome, it could be that your karyotype shows a mutation, such as a trisomy disorder. Since you said it was an "extra big chromosome," it must be one of the first, for they decrease in size.
