Answer:
karyotype
Explanation:
The correct answer would be a karyotype.
A karyotype is an image of isolated and purified chromosomes of an organism taking under the microscope. The chromosomes in the image are then cut-out using an appropriate instrument and then arranged according to their sizes from the smallest to the largest. From this arrangement, missing or extra chromosomes can easily be revealed.
The entire process is called karyotyping.
