15.4.2011 The genealogical ancestors to an individual are the the individuals that can be reached by a string of operators mother/father to that individual, like motherfatherfather. Within that set are the individuals, that has genetic material that was transmitted to the present individual. Genetic ancestry is in general given more attention as that is a component in genetic analysis and mapp...

This paper presents a method for building networks that highlight affinities, or inherent similarities, among people, particularly family members. The content of such affinity networks can be exploited to strengthen living families and to direct family history research. Preliminary results demonstrate promise.

The article deals with the problem of genetic and genealogical (genealogical) verification documentary pedigree Nilogovs, reconstructed by methods classical genealogy. Thanks to testing male female representatives genus Nilogov on DNA autosomes, it was possible genealogically confirm author his direct ancestor Semyon Danilovich Nilogov, who lived in XVIII century. object study is biological sub...

Genealogical networks, also known as family trees or population pedigrees, are commonly studied by genealogists wanting to know about their ancestry, but they also provide a valuable resource for disciplines such as digital demography, genetics, and computational social science. These networks are typically constructed by hand through a very time-consuming process, which requires comparing larg...

We conducted a 320 year retrospective survey of the history and genealogy of a large Brazilian family with SCA7. The ancestral couple was from the State of Ceará, Brazil, and the genealogical tree was composed of 577 individuals, including 217 males (37.6%), 255 females (44.1%) and 105 individuals of unknown sex (18.1%). Based on collected information, the 118 individuals consistently affected ...

The GEDCOM file format is by far the most widely used means of exchanging genealogical data and extensive collections of these files are available online. There is a huge potential benefit for historians and other academics who are able to make use of the data contained in available GEDCOM files, as these effectively represent hundreds of thousands of hours of crowdsourced work and a considerab...

Early in the development of plant evolutionary biology, genetic drift, fluctuations in population size, and isolation were identified as critical processes that affect the course of evolution in plant species. Attempts to assess these processes in natural populations became possible only with the development of neutral genetic markers in the 1960s. More recently, the application of historically...

The peninsula of Baja California has a complex geological history that has strongly affected the regional biota. Genealogical histories of many species have revealed congruent patterns, which suggest that the peninsula was temporarily submerged at two locations. We sequenced a total of 1953 base pairs (bp) of the mitochondrial genome for 42 specimens of the zebra-tailed lizard (Callisaurus drac...

Close relatives can share large segments of their genome identical by descent (IBD) that can be identified in genome-wide polymorphism data sets. There are a range of methods to use these IBD segments to identify relatives and estimate their relationship. These methods have focused on sharing on the autosomes, as they provide a rich source of information about genealogical relationships. We hop...
