Euclidean distance is commonly involved in calculating functional diversity (FD), for example, in measures based on dendrogram branch lengths. We point out that this function is inappropriate in many cases and that the choice of clustering method is more crucial than earlier thought. Gower’s formula and UPGMA clustering are suggested here as a standard combination of techniques for calculating ...

In this paper, we present a hybrid clustering method that combines the divisive hierarchical clustering with the agglomerative hierarchical clustering. We used the bisect K-means divisive clustering algorithm in our method. First, we cluster the document collection using bisect K-means clustering algorithm with K’ > K as the total number of clusters. Second, we calculate the centroids of K’ clu...

Bioinformatics emerged as a challenging new area of research and brought forth numerous computational problems. Here computers are used to gather, store, analyze and merge biological data. In this paper, the problem of clustering interval-scaled data and sequence data is analyzed in a new approach using Hierarchical Sequence Clustering. In Sequence clustering, it is necessary to find the simila...

Information on the genetic identity and interrelationships of different Morus spp. genotypes is essential for their proper conservation and utilization. Hence, the present investigation was undertaken with genetically more reliable DNA markers to study the genetic relationship among eleven selected genotypes of mulberry collected from Japan, India and Italy. Using ten RAPD and ten ISSR primers,...

Allelic patterns and genetic distances were examined in a collection of 103 foreign and Brazilian mango (Mangifera indica) accessions in order to develop a reference database to support cultivar protection and breeding programs. An UPGMA dendrogram was generated using Jaccard's coefficients from a distance matrix based on 50 alleles of 12 microsatellite loci. The base pair number was estimated ...

Seven STMS primers were used to analyse 20 individuals each of 15 populations of North-western Indian Himalayan hull-less barley landraces. A total of 96 alleles were detected of which 40 were common and 56 were rare. Administrative regionwise, highest allelic richness was revealed by populations from Himachal Pradesh (10.71 alleles/locus) followed by Jammu & Kashmir (8.86 alleles/locus) and Ut...
