WebCytogenetic analysis is the study of the banded pattern of chromosomes during metaphase of the cell cycle. It is carried out on a cell-by-cell basis, and hence mosaicism is easily recognized when only a few cells carry the chromosomal abnormality. This analysis can detect large-scale chromosomal abnormalities, most commonly aneuploidy. WebJul 30, 2015 · Cytogenetics Normal human cells have 46 chromosomes (pieces of DNA and protein that control cell growth and function). Some types of cancer have one or more abnormal chromosomes.

Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis. Techniques used include karyotyping, analysis of G-banded chromosomes, other cytogenetic banding techniques, as well as molecular cytogenetics such as fluorescence in situ hybridization (FISH) and comparative genomi… WebCytogenetics definition, the branch of biology linking the study of genetic inheritance with the study of cell structure, especially for human chromosome analysis for the detection of inheritable diseases.
