... number of algorithms have been developed for calculating the quartet distance between two evolutionary trees on the same set of species. The quartet distance is the number of quartets – sub -trees ... algorithms make use of the sizes of the leaf sets of the rooted subtrees of the input trees, either directly or indirectly. Rooting T in an arbitrary...

... this study is to investigate the relationship between the co- efficient of disequilibrium D  and the genetic distance and to assess the impact of inbreeding. The choice of D  is justified for several ... the reduction of the number of alleles is caused by the high level of inbreeding, we expected this relationship. Therefore, to reduce the proportion and the...
