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 ...
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 ...
Interploidy hybridization is a term to describe a hybridization (or manual cross) between two different individuals of different ploidy levels. Individuals resulting from this type of hybridization are called interploidy hybrids. [ 1 ]

Diploidization is the process of converting a polyploid genome back into a diploid one.Polyploidy is a product of whole genome duplication (WGD) and is followed by diploidization as a result of genome shock.
Most modern aptamer selection methods strive to improve the conventional SELEX aptamer search method. [30] Despite the publication of various methods aimed at increasing the affinity and specificity of aptamers, [ 31 ] [ 32 ] [ 33 ] experimental approaches face limitations in the number and variety of sequences that can be examined and selected.
