Aberrant segregation was first clearly noted in the 1950s in genetic studies of certain fungi that allow direct examination of their four haploid products of meiosis. Normally in these fungi, a ...

Recombination events in many organisms are concentrated in highly localized areas termed 'hot spots'. Hot spots can be detected by statistical analysis of genetic variation, analysis of pedigrees ...

One of the key stages in the evolution of different sex chromosomes is a loss of recombination—the exchange of DNA during meiosis—that is both an important mechanism for maintaining genetic diversity ...
