Introduction The Dutch DBC-system was developed and implemented between 2000 and 2005. When compared to other members of the 'classification family tree' it can be concluded that the system is not a logical step in the general line of development of classification systems. On a number of characteristics the Dutch system stands out from the other systems. One major differing characteristic being...

The concept of Genealogical Sorting Indexes (GSIs) was first introduced by Cummings et al. [1]. Given a set of observations belonging to different groups (represented in the form of a hierarchial tree), the Genealogical Sorting Index (GSI) value obtained for a particular group provides a quantitative measure of how closely the observations belonging to this group have clustered in the given tre...

We present a machine learning approach for estimating missing temporal attributes in genealogical data. Genealogy analyses have been commonly focused on understanding generational relations. The importance of temporal analyses has often been suppresed in genealogical research. We have observed that temporal attributes of an individual, birth, death, marriage and divorce dates, are frequently mi...

The Ukrainian Riding Horse breed is the leading of horses in Ukraine direction sport working capacity. A long period breeding improvement requires establishment parameters that will continue process, taking into account modern needs classical equestrian sports. Studies were conducted on entire livestock breed, which kept by subjects and private owners. Quantitative indicators are established, a...

We have developed a 'Scan-Add-Print' database system, SAPling, to track and monitor asexually reproducing organisms. Using barcodes to uniquely identify each animal, we can record information on the life of the individual in a computerized database containing its entire family tree. SAPling has enabled us to carry out large-scale population dynamics experiments with thousands of planarians and ...

Ease and accuracy of typing, together with high levels of polymorphism and widespread distribution in the genome, make microsatellite (or short tandem repeat) loci an attractive potential source of information about both population histories and evolutionary processes. However, microsatellite data are difficult to interpret, in particular because of the frequency of back-mutations. Stochastic m...

The field of phylogenetics is entering a new era in which trees of historical relationships between species are increasingly inferred from multilocus and genomic data. A major challenge for incorporating such large amounts of data into inference of species trees is that conflicting genealogical histories often exist in different genes throughout the genome. Recent advances in genealogical model...

A variety of results for genealogical and line-of-descent processes that arise in connection with the theory of some classical selectively neutral population genetics models are reviewed. While some new results and derivations are included, the principle aim is to demonstrate the central importance and simplicity of genealogical Markov chains in this theory. Considerable attention is given to "...

The Sorenson Molecular Genealogy Foundation is building the world’s largest database of correlated genetic and genealogical information to enable genealogical research to be performed using DNA analysis techniques. DNA samples with associated 4-generation pedigree charts have so far been collected from approximately 40,000 volunteers. Up to 170 regions of DNA are currently analyzed for each ind...
