Explain what a karyotype is.
Expert Solution
Step 1 Introduction on karyotype:
Karyotypes are generally made from mitotic cells because they are found arrested in the metaphase or prometaphase, when the chromosomes are found in the most condensed state. A variety of tissue types can be used as a source of these cells. Karyotypes are often generated from peripheral blood specimens or a skin biopsy, also chorionic villi samples are taken for it. There are useful chromosome details which are tough to detect under a light microscope. Therefore for analysis, cytologists have identified stains which binds DNA and generate characteristic banding patterns for different chromosomes.
