Computer determination of the inbreeding coefficient, coefficient of relationship, and the ancestral composition in closed beagle colony

Proceedings of the 6th annual Southeastern regional meeting of the Association for Computing Machinery and national meeting of Biomedical Computing on - ACM-SE 6, 1967
A computer program, in FORTRAN, is presented for the calculation of numerical values descriptive of ancestry and genetic background of individuals. With appropriate information, this algorithm calculates the following parameters: ancestral composition, inbreeding coefficient, and coefficient of relationship.

Sex‐Specific Consequences of Recent Inbreeding in an Ancestrally Inbred Population of New Zealand Takahe

Conservation Biology, 2003
Abstract: Although the negative effects of close inbreeding in captive populations are well known, inbreeding in small, free‐ranging populations is less well understood. During the mid‐1980s, small numbers of the flightless Takahe (   Porphyrio hochstetteri   ) were ...

Ancestral inbreeding and inbreeding-purging models’ comparative analysis based on their classification efficiency of the Pannon white rabbit kits’ survival at birth

2023
The authors analysed 22718 kindling records of 5166 rabbits born between 1992 and 2017, respectively. The 25-year-long exanimated period was separated into three different sub-periods (1992-1997 ; 1997-2007 and 207-2017). The effect of dam and litter inbreeding on the survival of rabbit kits at birth was evaluated with two fundamentally different ...

Evaluation of ancestral inbreeding coefficients: Ballou’ s formula versus gene dropping

2005
Estimation of the purging of detrimental effects through inbreeding and selection is an important issue in conservation genetics opening new perspectives for the management of small populations. In 1997 Ballou proposed the ancestral inbreeding coefficient, which is calculated recursively via pedigree inbreeding coefficients, as a tool for evaluating ...

Ancestral inbreeding: Concept and Applications

2006
The present study is based on an incorporation of computer simulation and real pedigree analyses study. The first two chapters detail computer simulations. The third chapter is a description of a software program for calculation of several inbreeding coefficients by gene dropping approach.

Effects of ancestral inbreeding and kinship on cancer incidence

1999
One of the central issues in genetic epidemiology is to design a study that could simultaneously investigate effects of inbreeding and kinship on incidence of late-onset complex diseases. This study attempts to do it on the example of cancer in the remote island of Lastovo, Croatia.
