The 4 main points I’m not sure what u mean but if u refrase it
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!
