You can use a chromosomal karyotype to see if there are any abnormalities with the normal 23 pairs of chromosomes that every healthy human has. Different abnormalities like an extra chromosome (trisomy), missing a chromosome (Minos omg), or having certain parts missing or added on can lead to a person to be diagnosed with certain disease (ex: Down syndrome is an extra chromosome on the 21st chromosome).
Hope this helps!
        
             
        
        
        
Divergent boundaries occur where tectonic plates are moving away from each other. Mid ocean ridges are, as the name suggests on the floor of the ocean. Some divergent boundaries can be found on land. One example is in Iceland where the Mid-Atlantic Ridge surfaces. This region represents the area where the North American Plate is moving away from the Eurasian plate. Another example can be found in Africa along the East African Rift Valley.
