The methylene blue reduction test is a test commonly used to estimate the microbial load of a milk sample and as a result, examine the quality of the milk.
The principle of this test is that methylene blue is a dye which loses its colour in the absence of oxygen. Bacterial metabolism can cause the depletion of oxygen in the milk, therefore the methylene's reduction rate is connected to the presence of microorganisms in the milk.
As a consequence, if the tubes were not sealed tightly, then oxygen will enter the tube and the dye's colour will diminish, giving a false result concerning the presence of microorganisms in the sample.
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
