The study of whole sets of chromosomes is known as
Karyology
The traditional way for karyotyping involves adding dye to
metaphase chromosomes
… can be diagnosed from using dye with karyotyping
Down syndrome
In karyotyping, chromosomes are arrange in a standard format known as
karyogram or ideogram
Arranging chromosomes in pairs, ordered by size and position of centromere for chromosomes of the same size
karyogram or ideogram
The new karyotyping method use
