Geneticists use a technique called Karyotyping. Scientists take a picture of chromosomes and then arrange them in pairs to end up with 22 chromosomes and another pair that determines sex; chromosome (X,X ) for female or (X,Y) for males.
Then you can determine mutation when some chromosomes are missing, ex: missing chromosome 13 will result in Patau Syndrome, or missing chromosome 18 results in Edward's Syndrome

Can one get a chromosome count on dried blood?
It may be possible to extract genetic material from dried blood samples to obtain a chromosome count, but the quality and quantity of DNA may be compromised by the drying process. Specialized techniques and equipment are required for accurate chromosome analysis, and the results may be less reliable with dried blood compared to fresh samples.
How many chromosomes are found in a ophioglossum reticulatum?
Ophioglossum reticulatum, commonly known as the netted adder's tongue, has a haploid chromosome number of 2n = 720. This species has a high chromosome count compared to other plants.
How many pairs of chromosomes a daffodil have?
A daffodil typically has 12 pairs of chromosomes, for a total of 24 chromosomes. This is the normal chromosome count for daffodils.
How many chromosomes dose each parent pass to their offspring?
When a parent is going to have an offspring the offspring only gets half a chromosome from each parent, they combine to make one chromosome then that chromosome gets copied until there are 23 pairs of chromosome's. This is how you get your features.
What are some advantages and disadvantages of the serial dilution agar plate technique?
the total count includes dead as well as living cells
