Geometric fitness coefficients and inbreeding
Human Genetics, 19721. Under the assumption of discrete generations the general nature of the limiting behaviour of a genetic population is studied in case of gametic selection. 2. A comparison is attempted to compare an inbred (to an extentF) population with a random mating one with respect to rate of approach to the limiting structure which is in fact the

A Generalization of the Inbreeding Coefficient
Biometrics, 1965SUMMARY It is shown that generalized quantities of inbreeding coefficient and of coefficient of parentage for linked loci tranisform through two kinds of matrices. As an example, expressions of a generalization of inbreedin-g coefficient is obtained for three linked loci, and recurrence relationships of the same quantity for an arbitrary number of ...

The estimation of inbreeding from isonymy: relationship to the average inbreeding coefficient
Annals of Human Genetics, 1984SummaryThe inbreeding coefficient estimated by the isonymy method is often much larger than the average inbreeding coefficient (FD). One reason commonly stated is that the surnames are polyphyletic in origin in such cases. The purpose of this paper is to examine the relationship between the inbreeding calculated from isonymy and the average inbreeding ...

On the computation of inbreeding coefficients
Annals of Human Genetics, 1978SummaryA method of calculating inbreeding coefficients is described using a recursive algorithm. This has been programmed in ALGOL 68 and in SNOBOL 4. Advantages and disadvant, ages of this method are discussed, and several examples are given.

Theoretical and Applied Genetics, 1996
The relationship between inbreeding depression and inbreeding coefficient (F) for several important traits was investigated in an 11-year trial of maritime pine (Pinus pinaster). Five levels of inbreeding (F=0; 0.125; 0.25; 0.5; 0.75) were obtained in a mating design involving ten plus-trees, or their progenies, as parents (total of 51 families). For F=

Studies on Inbreeding. V. Inbreeding and Relationship Coefficients
The American Naturalist, 1914The object of this paper is to call attention to the fact that inbreeding of considerable degree may exist in the entire absence of any kinship between the two individuals bred together, and to bring forward a method of separately measuring what proportion of the observed inbreeding in a particular case is due to kinship of the parents, and what to ...

401: The Calculation of Inbreeding Coefficients
Biometrics, 1975A computer program has been written which will calculate the inbreeding coefficients in any irregular or regular mating system. This program has the following advantages: (a) it lists all common ancestors and their contribution to the inbreeding coefficient of the individual being studied, which allows a complete pedigree analysis; (b) the inbreeding ...
