Understanding the relationship between the inbreeding coefficient and multilocus heterozygosity: theoretical expectations and empirical data

open access: yesHeredity, 2004
Geneticists have been interested in inbreeding and inbreeding depression since the time of Darwin. Two alternative approaches that can be used to measure how inbred an individual is involve the use of pedigree records to estimate inbreeding coefficients ...

Geometric fitness coefficients and inbreeding

Human Genetics, 1972
1. 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, 1965
SUMMARY 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 ...

On the computation of inbreeding coefficients

Annals of Human Genetics, 1978
SummaryA 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.

The estimation of inbreeding from isonymy: relationship to the average inbreeding coefficient

Annals of Human Genetics, 1984
SummaryThe 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 ...

Networks of inbreeding coefficients in a selected population of rabbits

Journal of Animal Breeding and Genetics, 2020
AbstractThe correlation between pedigree and genomic‐based inbreeding coefficients is usually discussed in the literature. However, some of these correlations could be spurious. Using partial correlations and information theory, it is possible to distinguish a significant association between two variables which is independent from associations with a ...

Studies on Inbreeding. V. Inbreeding and Relationship Coefficients

The American Naturalist, 1914
The 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 ...
