Chromosome analysis is a method that is used to identify chromosomal abnormalities also called as karyotyping learn more about the methods and results for analysis. Cytogenetics is a branch of genetics 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 fluorescent in situ. What is a karyotype test in this article in this article in this article sometimes, babies have an extra chromosome, a missing chromosome, or an abnormal chromosome chromosome analysis (karyotyping.

High resolution chromosome analysis requires the use of elongation methods to obtain a high percentage of prophase and prometaphase spreads the chromosomes are less condensed than in routine metaphase analysis and the number of identifiable bands is expanded, allowing a more sensitive analysis of the karyotype. Chromosomes & mtdna read about each of the human chromosomes and mitochondrial dna (mtdna) and the health implications of genetic changes information about specific chromosomes.
