Article Abstract:
A study obtained emperical data groups of intraspecific restriction site polymorphism in Drosophila to check the hypothesis obtained from coalescent theory. They checked whether the haplotype is a cladogram, whether the frequency in the sample that has information on the topological placement of specified haplotype is a cladogram, whether the frequency of hapoltype linked to the number of mutational links to other haplotypes is the cladogram and whether the geographic position can be employed to obtain topological placement of haplotypes in a cladogram.

Article Abstract:
Cladograms were prepared using data from restriction sites in endonuclease maps. They were used to represent the genetic tree of the DNA region being studied and come up with a nested statistical design model. It is suggested that the model may be used for determining relationships between traits that deviate from the population mean. Applications were made on two worked examples: amylase activity and isozyme phenotypes in the esterase-6 DNA regions of Drosophila melanogaster.

Article Abstract:
An algorithm approximating cladograms representing haplotypes with a high probability of linkages is presented as an estimation procedure. Parsimony limits are first evaluated before cladograms are constructed. The estimation technique also determines potentially recombinant haplotypes. If extensive recombination is proven, the algorithm partitions the DNA into sections with little or no intrinsic recombination.
