why are karyotypes important tools for genetics?
Karyotypes are pictures of a cell's chromosomes taken when they are the most visible (most condensed). The picture is then edited so that all of the chromosomes are oriented in the same direction, paired up, and then sorted into the correct numerical order.
A karyotype can easily reveal chromosomal abnormalities, such as missing a chromosome (such as in Turner syndrome), having an extra chromosome (as in trisomy 21), or others (having a deletion of part of a chromosome, a transversion, etc.)
