The method was first described in 2002 in the scientific journal Nucleic Acid Research. [2] The first applications included the detection of exon deletions in the human genes BRCA1, MSH2 and MLH1, which are linked to hereditary breast and colon cancer. Now MLPA is used to detect hundreds of hereditary disorders, as well as for tumour profiling.
Ploidy (/ ˈ p l ɔɪ d i /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here sets of chromosomes refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes ...
However, using Ks plots to identify and document ancient polyploid events can be problematic, as the method fails to identify genome duplications that were followed by massive gene elimination and genome refinement. Other mixed model approaches that combined Ks plots with other methods are being developed to better understand paleopolyploidy. [20]

This is also the most common pathway of artificially induced polyploidy, where methods such as protoplast fusion or treatment with colchicine, oryzalin or mitotic inhibitors are used to disrupt normal mitotic division, which results in the production of polyploid cells. This process can be useful in plant breeding, especially when attempting to ...

A polyploid complex, also called a diploid-polyploid complex, is a group of interrelated and interbreeding species that also have differing levels of ploidy that can allow interbreeding. A polyploid complex was described by E. B. Babcock and G. Ledyard Stebbins in their 1938 monograph The American Species of Crepis : their interrelationships ...
