The routine chromosome analysis (Karyotyping) refers to analysis of metaphase chromosomes which have been banded using trypsin followed by Giemsa, Leishmanns, or a mixture of the two. This creates unique banding patterns on the chromosomes. The molecular mechanism and reason for these patterns are unknown, although it likely related to replication timing and chromatin packing. WebCytogenetics is a single cell directed approach to study the whole genome of a given species. It is essential as genomes of all higher organisms are organized in chromosomes. In humans microscopic cytogenetics enables identification of numerical and gross structural chromosomal alterations and makes it an important diagnostic tool.
