Cytogenetics is actually a branch of genetics but is additionally a neighborhood of cell biology/cytology (a subdivision of human anatomy), that's concerned with how the chromosomes relate to cell behavior, particularly to their behavior during mitosis and meiosis. Techniques used include karyotyping, analysis of G-banded chromosomes, other cytogenetic banding techniques, also as molecular cytogenetics like fluorescent in place hybridization (FISH) and comparative genomic hybridization (CGH). There are 2 types of Techniques Karyotyping is the routine chromosome analysis (Karyotyping) refers to the analysis of metaphase chromosomes which are banded using trypsin followed by Giemsa, Leishmanns, or a mix of the 2. This creates unique banding patterns on the chromosomes. The molecular mechanism and reason for these patterns are unknown, although it is likely associated with replication timing and chromatin packing.
