The agglomerative method of Hierarchical Clustering continues to form clusters until only one cluster is left. Select this option to display the cluster number (ID) to which each record is assigned by the routine. The default setting is equal to 10 or if the number of records in the dataset is less than 10 then the default is the Minimum between the Number of Rows in the dataset and your current licensed limit. Use this option to define the maximum number of leaves in the dendrogram tree. If Draw Dendrogram is selected, this option is enabled. When this option is selected, Analytic Solver creates a dendrogram to illustrate the clustering process. See the introduction to this section for a description of all clustering methods used in Analytic Solver. The goal of clustering is to reduce the amount of data by categorizing or grouping similar data items together. The most useful similarity measures in this situation are: See the table below for individual i and j values. When the data is binary, the remaining two options, Jaccard's coefficients and Matching coefficients, are enabled. Hierarchical Clustering uses the Euclidean distance as the similarity measure for working on raw numeric data. Without normalization, the variable with the largest scale dominates the measure. Normalizing the data is important to ensure that the distance measure accords equal weight to each variable. If Raw Data is chosen, Analytic Solver computes the similarity matrix before clustering. Choose the appropriate option to fit your data set. The Hierarchical Clustering method can be used on raw data as well as the data in Distance Matrix format. The Data type argument can be found below. See the Common Options section of the Introduction to Analytic Solver Data Mining for descriptions of options appearing on the Step 1 of 3 dialog. Transposable elements constitute a large fraction of plant genomes and represent a powerful marker tool for genetic diversity studies.The following options appear on the Hierarchical Clustering dialogs. Here, the retrotransposon-based marker method inter primer binding sites (iPBS) was used to assess the genetic variation and intergeneric hybrid dynamics in the family Asteraceae by studying genera Helianthus, Echinaceae, Tagetes, Tithonia and Verbesina. Two selected iPBS primers (22) detected intergeneric polymorphism in the range 44.8% - 93.3% (mean 70%) and 85.7% - 100% (mean 89.5%) respectively. Moreover, iPBS markers allowed the genetic discrimination at within-species level between varieties of H. annuus (35.7% and 19.1%) but also between single cross’s segregating intergeneric hybrids (28.6% and 40%). The inheritance of iPBS markers and the parental genomes respectively in intergeneric hybrids of H.
annuus has been manifested by the non-random elimination of markers mainly of origin of wild species and the preferential inheritance of markers unique to H.

In conclusion, the iPBS method stands as a reliable approach for the evaluation of genetic diversity of Asteraceae germplasms and perspective for use in the breeding practice of sunflower and related species.Īdams KL, Cronn R, Percifield R, Wendel JF (2003) Genes duplicated by polyploidy show unequal contributions to the transcriptome and organ-specific reciprocal silencing.
