Ancestral inbreeding only minimally affects inbreeding depression in mammalian populations. [PDF]
Journal of Heredity, 1997 Inbreeding depression can be reduced, or purged, by selection against deleterious alleles. This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few.

This paper presents a FORTRAN IV subroutine to calculate inbreeding and kinship coefficients from pedigree information in a diploid population without self-fertilization. The user can specify the number of ancestral generations to be taken into account. It is thus possible to determine contributions of succeeding ancestral generations to the inbreeding

Inbreeding is omnipresent and unavoidable in population genetics. High levels of inbreeding result in a reduction of genetic diversity and inbreeding depression. The avoidance of inbreeding is a primary goal for the management of small populations and very important for the design of breeding programmes in order to create productive progeny.

Progenies from first-generation self, half-sib, full-sib, and cross fertilizations were generated to evaluate the magnitude of inbreeding depression for vegetative and production traits in strawberry. Tests were conducted to determine the linearity of trait mean depression with inbreeding rate (ΔF) over this range of inbreeding values, as an indication

SummaryIn this study, the effect of different measurements of ancestral inbreeding on birthweight, calving ease and stillbirth were analysed. Three models were used to estimate the effect of ancestral inbreeding, and the estimated regression coefficient of phenotypic data on different measurements of ancestral inbreeding was used to quantify the effect

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.

SummaryGRain is freely available software intended to enable and promote testing of hypotheses with respect to purging and heterogeneity of inbreeding depression. The program is based on a stochastic approach, the gene dropping method, and calculates various coefficients from large and complex pedigrees.

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 ...

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 ...
