WebA. Chromosomal disorders due to numerical abnormalities. Chromosomal disorders are due to the change in the number of chromosomes present. This can be categorised into various types: Aneuploidy: loss or gain of a chromosome. This happens due to non-disjunction of chromatids when chromatids fail to separate during cell division. WebDetailed chromosome maps of D. melanogaster were produced by Bridges (1935) and these are still in use today. Puffs are reversible structural modifications to chromosomes which result in the local decondensation of, usually, a single band. Some complex puffs may result from the puffing of more than one band.
