Is there more to the question? I'm not sure what this would be.
When chromosomes do not separate during meiosis is called nonjurisdiction.
Sometimes during anaphase, chromosomes will fail to separate properly.
The advantage of using a binormal nomenclature in the system of classification is it formally names animals of a species of living things by giving a two-part name which either is based on Latin or other languages. One Part is used to classify the genus and the second part of the specific name. An example of this would be Homo sapiens (for humans).
