If the cause of the anaemia remains unclear, referral for bone marrow examination, including cytogenetics, is advisable. This technique is often used in cancer cytogenetics.

This is done by examining the appearance of the malignant cells with light microscopy and/or by using cytogenetics to characterize any underlying chromosomal abnormalities.

Nuclear status and cytogenetics of embryos derived from in vitro-matured oocytes. From chromosome shape to chromosome mapping: 30 years of domestic animal cytogenetics. If the cause of the macrocytic anaemia remains elusive, referral for bone marrow examination, including cytogenetics, is advisable. The symposia are classified under nine headings: clinical genetics (two meetings), cytogenetics, biochemical genetics, immunogenetics, population genetics, human evolution and computer methods. Prenatal cases with known mosaicism identified by conventional cytogenetics will be extremely useful in testing the accuracy and sensitivity of this emerging array technology. All aspects of human genetics are covered, including biochemical genetics, clinical genetics, cytogenetics, formal genetics, immunogenetics, population genetics, and behavioral genetics. Interphase cytogenetics solves some of these problems, but accuracy is reduced when more than five chromosome pairs are analysed due to overlapping signals. They include some reductions in strategic work on crop physiology and grass cytogenetics and carried out with funds from the science budget. From the Hansard archive Example from the Hansard archive.
